Cagiva Planet

[Seraphim]

Actually, the day after xiao boon tunes up the bike, the throttle response always seems smoother, with less hesitation on the revs when the throttle is cracked open.

 

After a while, the carb slide and jets get gummed up again and the slight, almost imperceptible jerkiness of lousy low end throttle response starts up again... bleh

Sounds similar to my piston/block replacement at minerva as well. Had fuel/oil leaking from the block.

 

did eugene say anything about the double piston rings availability? seems you have to get them in a set, meaning the piston plus the double rings.

Since Excel has plenty of single piston rings, i was persuaded further to change mine to a single ring piston. although planet's piston would have been cheaper by $100.

sad to hear about your problem terry, but now.. whoa... yur now running a mito engine on planet's 6 gears? sounds coolz! more top speed?

 

my recent problems, nah.. i dun knoe wats wrong, but since my bike ain giving mi startup problems.. i think its still okie.

.

dun know about top speed, but the sound is different, so is the throttle response.

 

 

about your starter problem, hope you clean up the connecting points so we can get that part out of the way if and when your problem re-surfaces.

read thru the threads brudder.

 

 

recommended 2T => motul 600 at HKL ($18)

recommended petrol => RON95 is ok. rich guys pump RON98

Yo Man,

Problems regarding my planet again, hope u guys can help me out... ...

I cant start my bike, everything seem to be working fine except for my starter button, when i press e start, there was no response frm it... ...

My friend told me to open up my seat, and hit at a square thingy, den will start liao, I hav not try yet, coz my bike is left in other places, will try tml morning though, hope u guys can help if possible, thanks

check the following :

 

1) kill switch off (the red switch on the right side of the handle bar)

2) fuel tap on (a circular switch on the left hand side of the bike)

3) bike in netural gear (shouldn't cause a problem, but no harm in making sure)

4) batt low ? (verify with volt-meter. anything less than 12v, charge the batt)

5) push start, shift to gear 2, clutch in, start pushing. do not twist throttle. as you push, release clutch to biting point. once you feel the bike starting, clutch in. shift to netural. test the charging system with a volt-meter. as you rev the bike, the volt should go up to about 14v. but not more than that.

 

 

do the above in sequence.

with regards to this point, do it with the choke turned on.. it will have a faster startup response.. works for mi. !

 

btw .. u need help? we can come over see see if its not too far.

that will depend. if the bike is jetted correctly, a cold start would need the pull of the choke. if it is jetted rich, probably will give you a good workout pushing the bike without it starting.

 

since zellus left the bike overnight, ya, probably a pull of the choke would be needed.

 

dun panic ah. should be small problem.

 

ya, where's your MGR? dropping by anin't a problem if it is near. PM your location.

[Gauntlet]

terry.. i am only doing 120+km/hr with

front 14 rear 46 teeth sprocket..

is that supposed to be correct?.

i just cant break the 125 barrier!

 

same goes to another friend of mine..

also a planeteer.

not to even mention 160.... bleh.

 

is it the sproket problem?

46? must have really good pick up huh?

 

mine is on a mito rear sprock. it's 41 if i rem correctly. front is size 14.

 

the rear sprock is really cheap at chong aik ($25). so is the front ($16). generic brand, made in thailand. and it's quite good value for money. the build quality is quite good, so dun worry. cheap and good leh. but of cos not as light as afam or renthal.

 

when you get the rear sprock there, be sure to see if it fits before you leave. i had an issue with the sprock due to the alignment of the holes with the screws on the bike. jus check before you leave the shop.

 

160 is not a problem on the rear 41, but pick up suffers. so you decide. mine was 160 plus on the second link (clock by an R1 and SP1). not the dodgy speedo we have.

[Gauntlet]

will a F 14 R 39 do a better job in top speed? ?... heheheh...

 

:sweat:

[biscuit]

Is there a general problem woth the planet in reaching higher speeds? cause mine can't seem to go beyond 110kph, not sure why. If it has to do with the sprocket size(s), can someone explain a little more? Also, my rectifier seems to have burnt out, any idea where can i replace it and roughly how much? thanks!

reasons could be

 

1) bike is not derestricted. get it done at minerva or excel cycle. unless yours is a fairly new bike. it is unlikely it is still restricted

 

2) stock sprocket size is 43, reaching speeds above 120 will not be a problem. so check what size is yours by looking at the sprockets.

 

3) loss of compression. symptoms includes when you shift from 5th to 6th gear, there is no noticable acceleration increment.

 

4) CTS valve needs cleaning. DIY instructions on this thread, if not get bike shop to clean it. clean your carbs at the same time. $40 for valve and carb clean at excel cycle

 

5) speedo spolit. get a friend to clock your speed.

 

i would suggest you to do step 4 1st. since you would need to clean them anyway.

 

how do you come to the conclusion that your rectifier is burnt? what symptons did the bike show for you to come to this conclusion?

probably. plus your acceleration would be that of a 50cc motorised bicycle.

My battery doesn't recharge while the bike is running. At first I thought it was a battery problem, but the battery is new and the problem resurfaced even after the battery was fully recharged. After about a day or two the battery was almost drained. It could be a rectifier fault as well, will probably get both changed. thanks for the advice!

wah.. so seious arr.

then cannot climb slope arr like tat?...

kekeke... better confrim man... before i go for the F14 R39, or 41 is the safest bet?

how slow is your accleration now at 41? is it very bad at slopes or normal startup got problem? i dun need a lean mean pickup monster ... kekeke

 

compression how to check?..

maybe u try to ride my bike to see if compression still correct?

where u live biscuit? might wanna pm us , then we pay u a visit, check stuff or better still go bike shop to repair ...

did u check your charging voltage with a voltmeter?

maybe there is a electtrical leakage in your bike somewhere?..

something is draining away that precious charge in your bike?

 

could be headlights, faulty erp unit, extra external devices,

i make is a point to switch everything off when i leav it for parking

 

All off are

1) lights (to off postiton)

2) kill engine switch

3) fuel cork switch

4) external switch for external devices

5) igintion off and lock

 

could it be when u switched off ignition , u left it in a position where in wheel lock mode it can still emit a parking light.. with headlights switch on? (i rem there is this option after the wheel lock turn of the key and small turn activates it) just cant remember wat name.. if this mode is turned on... its draining off batt also..

(not sure arrrr dun flame mi.. )

 

used to have your problem last time.. but i switch batt and do the above and its okie already..

might wanna try and let us knoe again.

Really appreciate the concern and advice you guys have been giving. ok went down to excel to have them look at the bike, turns out the problem was that the shop where i got the bike from didn't insert the fuse that recharges the battery. sigh. also the valve was incorrectly installed, causing it to open at lower speeds and close at higher ones, which was the reason for the low max speed; and to top things off, the front tire was installed backwards, with the rotation arrow pointed the wrong way. Got all the above problems fixed, but will have to go down again to have my loss of compression problem fixed.

 

Have one more problem though, was on my way back when i think i kena pistom jam. Suddenly the bike lost power, luckily expressway was clear enough to drift to the road shoulder, after a few minutes the bike could start again and i limped back home. Any advice on how to deal with this problem? thanks.

hmm.. maybe out of petrol or .. maybe your fuel area there forget to turn on?

or fuse broke again?

 

"but will have to go down again to have my loss of compression problem fixed"

 

can u ask him how he knoe compression is loss or not ?... visual inspection or instrumentation inspection? or as least wat method he used to determine compression lost?

 

i would like to knoe also if mine is because of the same thing...

was running on the SLE when suddenly the bike seemed to engage engine brake, then no response from the throttle. fuel light didn't light up, and i checked the tank, so don't think it is a fuel problem. When i stopped on the shoulder to try to restart the bike, it only started after a few minutes.

 

as for the compression problem, the mechanic there used a sort of gauge which he attached to the engine, and when he revved the engine. he indicated to me where the pointer should be if there was no problem, which was around 200? can't remember the exact number, but mine was way below that, which indicated loss of compression. hope that helps.
