Anyone know where i can get a set of clutch friction plates for a 1988 route 66 (xv 250) i can find plenty of places that sell the 95-00 version but not sure if these will work in an 88 model i need them asap as im due to go on a long run very soon and dont fancy breaking down as my clutch starts slipping in 4th & 5th gear so need to sort it quickly thanks

Have you tried damerrells or jim patch

Someone on another forum suggested it could be my oil as ive recently changed it.

Its proper bike oil 10/40 synthetic perhaps i should have got semi synthetic and possibly 20/50 but would changing the oil again cure it or would there be too much damage to the plates as it only slips in 4th & 5th gear but if i coax her gently then theres no slippage?

Full synthetic will make the clutch slip unless its desighed to run full synthetic
had the same thing on my zx9r hit 10,000 rpm all noise no go

Your most probably better off using 10/40 semi synthetic. But all said oil that says it designed for bikes shouldnt make your clutch slip

This bike is trying to test my patience now...... was going around a corner slowly thankfully when i got overtaken by............my front sprocket the bike had new sprocket and chain fitted a week before i got it so the bolts obviously were not tightened up properly or loctited. Thankfully all the bits fell inside the side case apart from 1 bolt and the sprocket its self. So sat on the road put it all back together with just 1 bolt attached to the sprocket i slowly rode it to my local garage bought some loctite and scrounged a new bolt so fixed now just glad i wasnt going fast or on the motorway as the chain would have totally wrecked the bike

Another possibility if you cannot get plates is to change the springs it is possible they are weak.

It's a good idea to ensure you put the right "Lifeblood" in, and some of the numbers on the can are real confusing - pure science with some of these oils!

I have a link but need to submit this beforehand - something to do with bloggers etc...

Fully synthetic will not make the clutch slip. Only using non bike oil (or oil for dry clutches) will make the clutch slip as bike oil has additives in it for running wet clutches.

Fully synthetic WILL make your clutch slip
its a know problem for bikes that usually run on semi synthetic

i thought Fully synthetic was supposed to be better

It is. But ONLY on bikes that are designed to run on it. It will not benefit older machines and can be positively harmful. Your machine is an older engine design, do not use fully synthetic.

ah the age ol debate

if car engine oils make your clutch slip, thenwhy doesnt it slip if you use slick 50 in the bike!!!


huh answer me that one!!

for years as a courierI rode any ol shed that came to hand in the morning, andI always ran them on £3.99 for 5l oil from the local garage

no problems

and my last minter Z1000 was treated with slick 50, so if anythings gonna make the clutch slip then surely this will
