Gilera Runner - FAQ 2012

[lucius]

a casual google check provided me this with result.

For 4stroke engine.

Valve clearance refers to the small gap between a valve lifter and a valve stem that ensures that the valve completely closes. On engines with mechanical valve adjustment excessive clearance will cause noise from the valve train. Typically the clearance has to be readjusted each 20,000 miles with a feeler gauge.

Yup. Tat'a right. Anyone had try doing the clearance before? I guess the bike should have a better power delivered after doing it.

[Suede]

not yet i do not know it is required to be cleared at interval of 20k miles!!! new info for me. thanx!

Haha.. You be doing it? Which shop u usually went to service your bike? Haha

[white_angel]

yeah i was asking myself the same question since i'm also in the park

for a new timing chain.

can't seem to find any post on ppl doing valve clearance & replacement

of timing chain since on the left side carb you only see an auto tensioner..

i have yet to see any scoot shops providing this service.

IMO valve clearance & timing chain change is essential for 4 strokers.

if you guys have any luck, drop me a pm.

of cos the competent mech would also need to know which leaf to

use (distance/thickness or watchamacalit)

Pros should be easier start, better fuel consumption & overall better ride quality.

yup.. Definately for all this pros.. Haha.. But in the gilera runner manuel did state any stuff regarding the need of valve clearance? Tot of looking into it too.

[white_angel]

i would have done it myself if i knew what the clearance measurements were..

engine has to rotate for it to hit (excuse the pun) TDC before adjustments can take place. any scrammie shop would do it on a regular basis.

am surprised that no one in this forum has done it yet.

I would suggest tai hin since only the faithful ones go there..

Yup, tat's right. Two of my friends riding drz already did the valve clearance. And they have give positive feedback regarding it. But will tai hin know about it? If I am not wrong every 4stroke machine require this process in order to maintain well the engine.

I'm looking the same information too. As far as I know Ducati bike every 24,000 KM need to do valve clearance inspection and adjustment. Do we have any information how to do it?

Hi, seems like runner dosent require valve clearance? Haha couldn't be I think. As overall is still a four stroke machine.

Hi,

Since scooter always running in higher rev, I believe our engine need to do valve clearance adjustment same like any other super bike.

 

e.g.

http://www.r6messagenet.com/forums/r6-how-guides/14272-how-valve-clearance-check-adjustment.html

 

Now come to the question. How we able doing adjustment?

 

Thank you.

Hi,

I found some useful info from this website.

http://www.modernvespa.com/forum/topic48015

 

On my gilera runner VRX200 ( same engine as vespa gt200 ) I found all valves had closed up abit on the 1st 4000 miles inspection

 

Set to the book settings of 0.10mm & 0.15mm metric

 

I believe 0.10mm for Intake & 0.15mm for exhaust.

Good and clear info. Thanks:) probably will check out with my mechanic regarding this. I know to know whether 4 stroke valve require polishing as in servicing like 2 stroke valve as well in the process of valve clearance?

Nice. I was thinking of doing it too. Maybe next week. I happenEd to meet up my old mechanic, he say he is able to do the valve clearance for runner. I will try to get some pics as well through the process of doing it.

bro, let me know the outcome of the valve clearance. Oh and not forgetting where and how much.

[killatequila]

hey guys wanna thank everyone before hand for helping me here! haha. ok im riding a nsr rr right now but wanna change to a runner. i definitely know more abt 2b sports bikes but almost nth abt scooter. im scared if i buy a runner i might get conned! or something wrong i also dont know.

 

can u guys help? just wanna know how's the maintenance wise? wat are the standard stuff have to change or look out for? i know there are no chiong parts for runners like nsr has. so roughly how are the costs? and i know there's the st/vxr200 and the 180 sp, wats the diff for these 2 models(besides 2 stroke and 4stroke)? which would u recommend? and if its 2 stroke can u still change to lv exhaust?

 

thanks again!

[rastadan31]

Pm me...will info u about it...ma no. is there too...

[killatequila]

thanks rastadan for your great help! any other opinions out there?

[dotdotdotzz]

Just 1 thing i wanna say. This Bike here is quite hot for a 2b bike. but aftre i change pipe then its get way much cooler.

[killatequila]

yeah but the 180 cant change to like lv exhaust! thats what makes me lean to the 200 haha.

[revontulet]

Hi confusehaha.

 

i know this is an old thread but im having the same problem as you did. My 07 st200 travels a maximum of 150 when everybody else says its ard 220km for full tank. its terrible. I just had my autochoke and some torn rubber fixed today but this is like a multiple attempt to settle to the problem to no avail. Did you manage to solve yours??

 

And also should i attempt to fix the fuel guage thing as suggested? will it be accurate after that?

[dotdotdotzz]

Bro. Advise u to go a scooter speciallise to let them see. i did mine at mach speed =)
