This scooter is messing with my head,adjusted timing to 21degrees and sounded like a bag of bricks so took it to 20 not bad now,did the choke test at 60mph see what it was like with a 124 MJ in no difference maybe a touch better so I went to a 132,134 and now the biggest jet I've got a 138,getting colour on the plug,1st,2nd 3rd runs smoothly and quick,4th still hesitant at 50mph but as soon as you get past it it dunna run to bad,dropped the mix as well to 2%,I'm thinking the jetting is too big,carbs off at weekend replace gasket and have a mess again

I'm running a Malossi 166 kit,28mm phbh carb,it runs sweet just that I come across one and wondered if my scooter would benefit from fitting one?

That's the problem I was having it was struggling over 50mph,it was set at 19 because I thought that was the timing on a mazzy crank?I'll adjust and get back to you with the results

That's rested my mind a touch because it was a new plug and only done about 15 mile on it,the old plug looked OK just a touch rich but the problem was a slight hesitation getting over 50mph,sorted the slide now opens fully,I've gone from 126 down and the 120 felt the best but not 100%??it's got a dr177 kit on,ported,21 tooth clutch,drilled filter,sterling pipe,57mm mazzy crank and 1.8kg flywheel and running a 24/24 carb.been checking out everyone else's jetting and it's around 118-120 so hopefully be safe,also running 3% premix at the moment because only done about 400mile after the rebuild

Just been out not entirely happy with that,pulls like a train in 3rd 55mph easy but in 4th going steady and going past 50mph-60mph seems to be struggling,gone back to 160,be5,118 and 50/160 see how that runs cus that ran the best with a 120 main jet in,still not happy with the plug still on the white side???

Also how many miles should you do to take a decent reading of a plug colour?cheers

Been out messing today runs OK on a 122 but still a bit hesitant over 50mph dropped to a 120 a little bit better and a be5 mixer going back to a be3 and 118 see how that runs,gotta bit of colour on the plug only a touch though with swapping from a be3 to a be5,is there much difference in a be3 and a be5 mix tube?cheers

Been tinkering all afternoon and with a few modifications and adjustments to the set up I've finally got the slide to open fully,going take it for a run tomorrow see how she goes,it was down to the autolube restricting the whole movement of the slide to fully open,so removed the link and changed connecting rod back to non autolube and adjusted the cable to suit,cheers for the input fellas

I'm going have a mess with it later,I've got a 26/26 so going compare different parts

Are the throttle slide connecting rods different lengths on a 20/20 carb and a 24/24 carb?
|

Post by kidda on Apr 9, 2016 21:40:30 GMT
This is what has got me thinking that it's not opening fully because of the problem with struggling over 50mph,it was a 24/24 non autolube carb and I swapped the rod from a 20/20 carb so I could use the oil pump link as a pivot and not change the whole setup,going have a tinker over the next few days,any input well appreciated fellas

Just a quick question should you be able to see the throttle slide when the throttle is fully open?or should you see say a quarter of it?cheers

If the timing was out would it run rough through the gears?

Plug was ok and a nice colour on the B8,thought I'd make some adjustments try and solve the struggling past the 50mph mark and was running better but then pulled the plug and seen the colour,lucky escape I think,I've gone to a 122 then take it for a short run see how it goes

Would a dodgy regulator make any difference to the running?

Pilot jet that was in was a 50/160 and looked bent slightly(maybe my eyes) ???swapped for a 55/160 and one turn out on the mixture screw and just been for a spin,throttle seems responsive and picks up well. I've got a 52/140 I can try but going run at this for now and keep an eye on the plug but seems alls well at the moment fingers crossed
