[240gordy]

Im in the process of building a 370r i have everything i needs pics of the build will be soon i have everything i need but ignition and paddles could use some info on ignition set ups. Im Stuck on paddle size i went with a 4 over swing arm. should i run 8 or 10 paddles i weight about 160 what would be best any info would help. i plan on running alcohol eventually.

9 or 10 pdl hauler works well on my 370. CR igntion is really the way to go IMO. If you are going to be doing some hard duneing then get a PWR or similar oversize rad just for the extra protection. Anything from a 39mm PWK Keihin to a 50mm lectron will work on a 370 depending on what you wanna do....

If you haven't bought the jug already I'd consider a CP sphinx cylinder. Sounds like you already have the jug though. I've had lots o trouble with my 370, specifically internal coolant leaks from the sleeve moving.

I run 9 paddle superlites on my sphinx and its hooks up really well. I also had alot of problems with my ESR cylinder. Best of luck with it.

I just bought 10 paddle extreme haulers for my 431 Puma. I'm sure you could get away with running 9 or 10 paddles and still hook up fine! Thanks Higgy!

Don't believe everything you read. There is some good info here, but some misleading also.

I would be more interested in what hp/tq the motor is expected to put out, what type of power/riding you want to do with it, prior to making recommendations. I think I'm in the minority, at least here, but I've had no issues with my older casting ESR cylinder.

Yeah true... i think im gonna go with a nine paddle supper light thats what i kinda had in mind to begin with... does anyone know what a good sprocket combo is??

The Older Castings from ESR are not the problem... they were Pro-X castings. Its the new ones supposedly done in house that are troublesome.

Mine is the 'old style' ESR pro x and it has been a major PITA with coolant leaks, sleeve movement from brand new. Who knows maybe it was just a lemon lol.

I think superlites only have one size. But they are 22 tall with 72inch roll out
