Best YPVS Mods for Reliability

[jonno]

Anyone got any recommendations for exhaust, filters etc. for a YPVS motor, that give the best allround performance without compromising reliability too much.

Thanks.

Norbo's guidance on this is
lightened flywheel £60
F2 pipes £250
boost bottle £25
carbon reeds £24
jet up 2 sizes £6 all parts from Norbo (prices are approx)
keep the filter and air box

If i'm wrong Norbo please correct me as my memory sometimes plays tricks

Do K&N's do anything or do they leaken the mixture by to much or anything?

I think you lose some bottom end - but gain max power - so it depends how fast you ride - are you throttle to the stop? - or do you prefer to pull?
Then again - stuff that they look good and sound good

I dont have the original airbox so i think ill stick with shiny K&N's.

Im not a fan of filteres. If i have to put them due to tuning or an air box just wont fit then i will . Filters take away bottom end and give a little mor right at the top. The main down side with them is They make the bike a little fluffy on the thotel and jeting can be a nightmare. When its cold your bike runs week and damp it runs rough worm it runs fine untill night rolls in and it gets cold or damp .Sopme bikes seem to do allright with them on but by far most do not . They can allso make a hot spot on the piston crown leeding to sezure or in some caces they can bit by bit eat the piston head away untill you get a holl.
