Speedfight 2 jetting

[Jackward]

Hi everyone. Ive got a 2001 peugeot speedfight 2 liquid cooled derestriced with 8 gram rollers. I was running a technigas with a 72 jet in and the spark plug was a blacky brown colour. My exhaust broke so i fitted a stage 6 pro replica and it needs jetting up this is were i am having trouble this is what ive done so far

Picture 1- This is a new spark plug with and 85 jet after a 5-6mile ride then turned off at full throttle. The bike didnt bog when i let off the throttle then went back onto it. but going down hill at about 48 if i let off and go on it will bog. ive had an 82 jet in and an 88 but i didnt use new plugs and couldnt tell any difference.

Picture 2- is with the 88 jet in. I no this would be too rich and i didnt use a new spark plug but i couldnt tell the difference between the 85 and 88 jet.

Picture 3- this is with the 85 jet without a new plug

Do you think i need to go up from and 85 jet or down? im not sure what to do thanks for any help in advance

They all look sooty. I would go down a few sizes.

Actually, I wouldn't. I'd save the money, wait until you reach 17 and then buy a 125.....

AAsking the question 3 times will just piss people off, btw...

Did you get the bike sorted?
I have just completed a Speedflight2(LC) & although it has eaten up a serious amount of budget & time- it now runs very well- I believe it is capable of 70mph

If you need advice- post back- I will do my best.
