85 tri-z issue with gas leaver

[BiGDawG]

where you turn the gas on and off, for some reason while riding it keep moving its self to almost off i'll be riding and it will fall flat and try to stall reach down turn it back on good to go for a few more mins.. sucks having to keep reaching down to turn it back on lol, also not sure if its normal but full throttle down the road it vibrates so bad i can hardly hold the handle bar.

Broken piston skirt maybe?

[Bryan Raffa]

crank bearings, rod bearings? ect..... remove the 2nd petcock ... you dont need it

[oile]

Check and see if you have a bent axle or rim.

West Virginia Chrome it into place...works upto 100mph and comes in a roll for $2.00

i only have 1 petcock and it don't hop but i'll still check the axle, the rim's look like junk.. so that could be dose anyone have a good engine shot from the side the kick start it on? some one asked me if it had a bike engine in it

Should be easy to tell if you have a bike motor in it unless they modded the kick starter some how. The bikes kicked towards the rear and the z kicks toward the front. Ill get you a picture in the A.M if no one else puts one up by then.

[BiGDawG]

yea it kicks forward, and they got rid of the stock switch and overheat light just has a toggle down by the seat and headlights ant wired up

[90guy]

Sounds rigged up lol! Ill get you a pick once I'm done with work tonight!

Does it have a power valve?

[BiGDawG]

i feel dumb for asking but this is my first 2 stroke.. whats a power valve look like?

if i end up needing rim's what my best bet, the tires are like new so

Post a photo of the right hand side of your engine and cylinder and we'll let you know. Your engine came with provisions for a PV but they only came stock on the YZ bikes.

Its your foot hitting the fuel switch, if your wear high boots or have a tendency to pull the right leg up..it happens..could be wore out o ring and seals too causin it to be a bit too loose..iv shut myself down a few times with this issue i moved the pump to the backside of the mount.

[BiGDawG]

i'll grab a pic later today, and i don't think so i just wear normal shoes lol but maybe my pants flapping in the wind could be hitting it, but it dose turn really easy

also not sure if its normal but full throttle down the road it vibrates so bad i can hardly hold the handle bar.

Does it have the same vibration at full throttle when you are sitting still and not going down the road?
