Suddenly this thread was injected with Buy Buy Buy virus for Viffer exhaust...

Thanks Hamsterz, will try your way to dampen the side panniers mount. It is theoritically sound to me!

1. Drop the triple clamp by 8mm to quicken / lighten the steering without sacrificing high speed stability.

2. Bulb up to 90W/100W for $5 per bulb.

 

Cheap thrill la.

Is it worth it to lower the triple clamp?

What did you use to measure the fork?

Oh Yes. The lighter steering is great.

 

Why not try it, its reversible if you don't like it. But don't drop too much cos if u bottom out the lower clamp will whack the front fender. I find 8mm the best, although you can get away with 10mm max.

 

After dropping, and to retain the same bar to seat relationship, I clamp the bars to the top of the tube as per normal. Therefore you will not see any greater fork protrusion at the top of the bar. This will set the bar detente away from the retention gap of the fork top clamp. Some will think it is risky, but if torque correctly, I have no problem of the bar rotating even when the bike is dropped.

 

I use a protruding end of a vernier but any ruler can do. Measure from the top of the fork tube to the top of the triple clamp. Make sure both sides are exactly even.

Thanks, will try it out.

Did you lift the front to make the adjustment?

[Friday13]

Thanks VFRT...Will try it soon! I am sure this 8mm drop will bring me greater joy in my commute...

8mm sounds like a lot..... although i dont ride a vfr.

 

my other bike, even with 3mm dropped, it feels a lot of difference liao.... so maybe u might wanna start with a lesser dimension first. then adjust until something happens to u!!!!!

Do the adjustment gradually. Going straight to 8mm might be too much if you are not use to it. You're need to adjust the angle of your brake and clutch levels because the body position will be different.

Hi fellow V-4 owners, I own a VFR and so I hope that I can join in your group discussion,

 

I finally found vfrT , teng, remember I am Chris met on the track once with the black VFR

 

Some people have a weird problem of always looking at the temperature gauge, I am one of them , I mean I look at the temp every time I stop at a traffic light etc... also when traffic is slow

 

My question is that in some slow traffic , what is the most a VFR or RVF temp should be ?? My is farenheit NOT Celcius , I know Celcius boiling point is 100C , so what do most of your bikes doing , if anyone can help in Farenheit better still , my goes to as high as 242F , I have checked my bike, change to the best coolant, fan is working etc...... so is 242F normal ??? it translate to 116C !!!!

 

Thanks buddies !!!! V-4 is FUN !!!!

Hi smokey.. welcome to the Singapore VFR forum. Just to share something. A better indication of your bikes running temp (water) would be more accurate when the bike is moving at constant vel for sometime.

 

The reason is because measurements of heat transfer for close accuracy is best at equilibrium state, which will take some time to achieve provided the parameters are kept as constant as possible (for this case, would be heat o/p from engine, heat exchange between coolant and ambient temp/wind)

 

Traffic light start stops is one of the best way to mislead riders from comprehending the water temp. For cars, it is not so critical because their heat exchange system is damn good (just look at the size of the radiators!!) Bikes will definitely shoot up.

 

i cannot remember my running temps for day n night. (erm.. sold her liaos )

 

But its about 85~95 deg in the day and 78~85 in the night. As for tracck session.. its quite hovering abt 95deg. All the above mentioned temps were read at most constant parameters as possible. Staionary/traffic situations, i never read. They vary!

 

Hoep these helps. Just my 2 cents worth. Kindly feel free correct me if the above mentioned were wrong in anywhere .

The temperatures are about what I get, maybe a couple of degrees less.

But I'm curious how the temp can reach 116deg C... cos the fan cuts in at 106deg, and does a very good job of bringing the temp down quickly after that. I installed a fan switch, but have never even bothered to use it.

This I agree... The fan really does a decent job in getting the temp down esp when you are stuck in 2 successive red lights at 12pm on a cloudless day.

[Guest KISS]

I doesn't have much problems about the temp on the roads. It's the temp at the track that has been bothering me becoz it reaches to about 115 deg.

 

And when that happens, I have to go for a 1 lap of a 'cool-down lap' before I get into the pits. If not, coolant will be spilled over.

 

This has happens twice at PG. I don't have this problem at Sepang, due to its track layout.

u mean like these few days?

[sfowner]

These few days have been warm, but not too bad if we ride early mornings and late evenings... still can take the bike out, better than when it's raining cats n dogs...hahaha

Hey Speedy

 

 

On the dropping the triple clamp thingy, you guys should note that that raising the preload at the back also result in the same result -ie it quicken the steering albeit at a lower rate than by tweaking the front. However, raising the rear raises the overall height also.

 

I drop my front by 8mm and the rear shock is set at 3 clicks of the preload from the lowest. You guys may want to experiment.

 

None: Quote: Did you lift the front to make the adjustment?

Yes. Sometimes when I am lazy, no - for this I partially lossen 1 fork's pinch bolts at the top at bottom clamps while leavin ghte other alone to support the bike; then, pump the bike up and down until it is set at the wanted height then tighten that fork at the top clamp. Do the same for the other fork. When both forks are set, tighten all 4 bolts.

 

Your bars may be raised out of the detente slot at the top clamp. I just leave the bars as is to maintain the seat/bar relationship. You may want to drop it back into the slot.

Hey Chris

 

Nice to hear from you again. If I remembered, the first time we met I said the VFR is a crash worthy bike. Second time we met u tell me I am right ya? keke:cheeky:

Yes it is a curious thing.

 

The temp gauge and the fan thermostat swtich are not linked. The fan switch should kick in when the water temp reaches around 104C. Unfortunately, because of air lock at the fan switch location, the fan kicks in only at much higher temp as indicated by the temp cauge. The air lock acts as an insulator and separate the coolant from the sensing surface of the fan switch, so the water temp would need to reach a much higher temp b4 the fan sw cuts in.

 

The factory manual recommend that after changing the coolant, you should warm up the bike to ops temp and then blip a few times to purge the air before cap down. It seems to be not enuf for me.

 

So I took this 1 step further. After the above, I partially turn out the fan sw just enough to see bubbles appearing through while holding the engine at a constant speed, say 2000rpm. Once the bubbles have dissipated, tighten back down. Its the about same as bleeding the brake lines.

 

Make sure you bring up to ops temp to allow the thermostat to open and allow full circulation - especially after a full drain. Do not do bleeeding on a cold engine - it is not possible as the coolant are not fully circulating through the full system.

[ANR Impex]

Hi vfrT, I have worked on 2 VFR800, clearing the system of air is a simple affair. In fact, the system is self purging after a few warm up/cool down cycles. Smokey needs to ascertain at this point of time if his fan comes on at the typical 212F (100C) trigger point. If it doesn't, you might be right.

 

He also needs to check if his coolant cap is holding pressure by checking for boil over in the reserve tank and checking the coolant level by opening the radiator cap directly when the bike is cool. If the fan comes on but temp still climbs and there's full coolant in the radiator when cool, it suggests a thermostat (the valve that shunts hot coolant away from radiator) that does not fully open or a sensor not reading the temperature correctly. It is common for a bike with some age to have a stuck thermostat.

 

Also, Smokey needs to say what is his 'best' coolant, there are some really expensive ones out there that isn't worth anything in our climate. Glycol free is the way to go, there are a few brands out there.

Yup the temp at the track is scary, always more than 110 deg with fan on.

I had seen 124 deg before on my bike, immediately pull to the side and turn it off with the coolant leaking all the way!

 

Anyway that's the result of my first coolant flush gone wrong, after that flushing has never been easier.

[SMOKEYPIPE]

Hey vfrT , yep , I remeber you said that , but it is true, I carshed & it held well hee hee !! !! ha!! ANR Impex, you are very professional, and very right , the radiator cap was the problem !!! fan worked everything worked but the cap was not !!! changed to Honda original $30 ! worth it ! Many thanks for the inputs, in fact I am very happy to hear the V-4 rumble again !!!

 

I have been a VFR rider for so long 2 years, it the one bike that I never get tired off, sold off many bikes along the way, Ducati916,BMWsF650 suzukiGSXR600, yamahaFZS600 in last 2 years but still stuck to the VFR , wonder why , everytime the thought of selling it appears , the next second the thought of missing it comes along ha!!! how about a gathering of VFR 800 riders/lovers ????

 

Sure tempted to meet similiar thoughts personnel who can share the VFR passion ,

 

Shall we meet ?? Kiss , vfrT can arrange ?????

[ANR Impex]

Glad you solved your problem and thanks for your kind comments. I am a professional hobbist at this point of my career

Count me in if you guys want an all Viffer outing! I will definitely make it unless I am outstation for work overseas during the date.

Ya a ride is great, altho I think any non-viffers would be welcomed - especially Hamz who is still missing his V.

 

I initated something last week in here but got no response, so it was a solo blast to Malacca & back last Saturday.

 

Anyway I am game for anyone who has a proposal.

[Friday13]

Hiaz...Juz recieved news that my side panniers will be delayed again...KNN...Ride so long liao still haven get my panniers...WTF are the motordiams doing? From Jan delay until now... How to work like that?
