GK76a SP CDI

Post by BB_158 » Wed Apr 24, 2024 6:07 pm

Have a GK76a which I believe has been fitted with an SP motor & carbs. It starts and runs fine, and revs freely in neutral (above 8k). On a 10 mile test ride it pulls really strong up to 8k revs, then fluffs and won't rev any higher in any gear. Somebody who is into these suggested the cause is the wrong CDI, as they are different.

I've tried looking for an SP one but no luck. Does anyone know where I can source one or even borrow one to try?

Anyone experienced similar or any ideas what is going on?

Cheers
My other ride is another 400, Woohoo!... Doh

It is possible but that being said you have to match the reluctor(sp) to the the CID so that maybe the problem. I am sure there are people in the UK that mod them. Let us know what the # are on the unit- eg. 32900-XXXXX Someone with a parts book can tell you.

The SP motor will need the SP CDI, it's different to the standard GK76a one.
