Ive just ran my bike with a new set up and I’m finding problems with top end. Its a Malossi 210 with ported crankcase, 26/26 carb, lightened flywheel, racing crank, cosa 23 tooth clutch. Simonini pipe & standard gearing. Timing at 125 mark.
I was running before stet up with a standard crank & Sito plus and the scoot pulled all through 4th up to 75 ish mph. The bike now with new set up pulls well & does 55 ish in 3rd then just 60 mph in 4th.
I’m presuming that this is due to the simonini pipe with the Malossi kit pushing the power band towards the higher revs & in 4th the engine cant pull though to this band?
I’m in 2 mind whether to fit a T5 4th gear or preferably increase the power band so I’m not reving the heck out the engine on the Motorway or am I wrong to think this?!
4 topic questions :
Does an engine fitted with T5 gear rev v highly at motorway speeds 70 ish mph?
Would fitting an upgrade pipe ie RZ or SIP pipe alter the power curve enough to pull through in 4th with the present standard 4th gear? Is it worth £200 getting a SIP pipe anyway?
Would fiting a 28/30 PWK carb (ive got one on order) to standard gear set up & Simonini pipe also incease the power enough to get to the power band in 4th?
Ive not checked the ‚squish‘ dimension for Piston./Head clearance. Im running a machined head from Beedspeed for the Malossi with a copper head gasket to be on the safe side - Would reducing this dimension to 1.8-2.0 mm as specified make much difference to the power of the 210 thus pulling it better in 4th standard gearing?
Excuse the ‚war & peace‘!
Any suggestions/comments greatly appreciated.
Thanks in advance,
