Guide to timing my sigma 150 -also useful for 140 supersport

Hope it goes well, and I hope I haven't sent you on a wild goose chase!!

No problems, its easy enough to put back with the timing tools I made.
Im going to bet against 118 111 though

Just got off the RR

Made 145.6hp and 116lbft, power drops off towards the end

The chap overlapped the maps for comparison

Time to re-time to 118 111

Well, they say a picture says a thousand words
Funnily enough a TDC tool and new DTI arrived at the weekend so I guess I have another job on the list of things to do now - not sure when it'll happen though!
Thanks very much for taking the time and effort to do all this and sharing your results

No problems, it goes someway to sorting out the mystery timing!

Could you please comment on my other post regarding the breather setup of your 150?

If you need a carb syncrometer and mbe lead then I can lend them to you as your TPS and idle speed will change with the timing

I'm good for those bits but thanks for the offer.

Yep, no probs, I did read it this morning but couldn't remember how mine is connected but will have a look tonight.
