Hi

Bought a H with SP forks, could not a find a decent L or SP and missed Josh Daley's 79.8BHP beast!

I will be racing with Darley Moor and Aintree and looking to do the Manx in 2014.

I have just read the Manx regs and its states:Rebores to a maximum increase of +1.00mm above the standard bore size are permitted is there a max for F400 club racing?

Any other tuning advice greatly appreciated!

usually 1mm as 0.5mm are very hard impossibble to find now.my opinion Just run stds as not worth the extra cost for the increase.

as for tunning skim,port head,squish,ram air, decent exhaust and get the carbs sorted should see 72 ish real horses.

Dyna 2000 ignition? and was the L clutch a slipper clutch and will it fit a H engine?

All L model clutches are slipper. The steel plates are a different thickness but if you're changing the basket then not an issue.

Never used the Dyna 2000 ignition module.

sorry, so a complete L clutch will fit onto a H engine?

Petty exspensive and dont think youd get much benifit.All depends on budget.
get the motor tuned by Roger Middleton, chip cdi,decent system and get set up with ram air.thats the best budget option.if youve got spare cash then flatslides.adj ignition etc
