The Polini Sport and Stage 6 Streetrace produce similar power but the streetrace has a much wider powerband keeping maximum power at higher revs...
Totally agree Chubz, the difference is probably down to your Polini kit and my stage 6 kit which produce totally different powerbands.
This forum, or gumtree.
Mine did the same until I removed the snorkel. Basically it's overfueling and when you open the throttle it wets the plug. Using a 21mm carb is...
No the air mixture screw affects the idle jet only. The issue sounds like it's with the main jet, try going up one and see how it goes. If it's...
Put the airbox on and start from there. The airbox not only filters the air but rebounds the pressure wave from the previous stroke to help the...
Jet sounds too big I run a 70 streetrace with a 17.5 dellorto standard airbox (snorkel removed) and it has an 84 main jet.
If it's a fifty keep the snorkel on, in my experience you only need tit removed for a 70 kit as it draws 40% more air on each stroke. Do you know...
Remove the float bowl and see if the float is closing the flow valve too early, and while your at it give the carb a squirt of carb cleaner and...
It's probably the clutch springs.
The boost bottle is a total waste of time so bin it and while your there ditch the bellmouth. Your bike will run much better with a standard...
According to my manual its 14 degrees btdc at 5,000 revs.
Sounds like fuel starvation, have you checked the float level?
As long as theyre the right size it doesn't matter and 4.5g is a good start.
7 gramm rollers seem very heavy, standard is 6.5 and most derestricted bikes with a sports exhaust run between 4 and 5g which allows the engine to...
If it's upjetted that means that a bigger jet was put in. What has exactly been done to your bike to need an upjet?
No they run richer in hot weather so a smaller jet is needed. Hot air is less dense .
Quite possibly a jetting issue, if your bike is tuned with modifications to the carb then it could run rich in hot weather.
400 grade wet & dry and 600 between coats.
Theyre all LC. There may be a difference in the wiring and the carb, Otherwise it's a straight swap.
