one other option if all else fails...if you put a big flat head, in the big intake hole of the isolator and put the screwdriver blade tip up under one side and rest it on the otherside of the hole you mite be able to get under it. work your way around alittle and dont try to get it in one try. do not use the screw driver between the part and the engine it will mess up the sealing surface. could also try a thin putty knife flat between the two and a tap and it should come right off. atleast its a cheap part

PFS has the rockers for 69mm valves if that's what you need (part # 151-247).

I recently worked on a girls scoot where the Previous owner had installed a BBK but the rocker arms didn't match and they had the adjustments screws in all backward since they wouldn't reach. I happened to have an extra set of rocker arms that came with a BBK and installed them. Voila perfect fit. It's the rocker arms that are too short not the adjuster screws.

42/16 would be the least aggressive of the gears, but a big change over stock. If your gears are the same as mine that would take you from about 11:1 stock to 8.5:1. May be a bit much. I'm not really sure what these 4Ts like for gearing. I'd prob consider something like the gears that Scrappy sells that would get you around 9.4:1. Someone else that's used different gears on these may have another opinion though, and I'm basing this off of the gear ratios stock in my TaoTao.
Break in is not a big deal. I'd just make sure to change the gear oil after the first 20-50 miles and prob again at 500 or so.
You will need to get the gears pressed apart and together. Just in case you didn't know they won't just drop in. Local machine shops should be able to handle that no problem if you take them the stock gear and new one.

well i want the most bang for my buck that being top end and accelaration and i ownly want to do this once. and what do you mean it wont just drop in i cant just bring the local machine shop the whole engine i dont have the tools for dismounting il be lucky if i find a impact wrench and 3/4th adater for my scokets that will do the job in my price range [if you can recommend me a electric one please do so 80-100 bucks is all i can spend]

The intermediate shaft/countershaft is in the middle of the gearbox and it's got 2 gears on it. One has to be pressed off so the new one can go back on. That's all you'd have to carry somewhere. Small part. Ignore the numbers (first pic I came across of one), but it's in the pic below.  I think if you take a big jump in gearing you may be disappointed in the loss of acceleration, that's why I'd suggest sticking with the more conservative change. I don't have much experience with electric impacts to tell you which is good because I always use pneumatic. If no one else can give you a good recommendation a lot of times I'll get on amazon or a site that offers a lot of reviews to help me decide. |

but what is the goal of gearing ratio do i want the highest first number and the lowest second number what is the ideal set up in most cases

It doesn't really matter what the numbers are, but what the ratio is. Primary and secondary gear ratios need to be considered together to come up with a final drive ratio. Maybe this will help? 49ccscoot.proboards.com/thread/3472/primary-secondary-final-drive-ratioI haven't had the opportunity to play with a bunch of gear ratios for these yet to be able to tell you what they like. I know there are people on this site with upgears that could offer some experience, but unfortunately they haven't chimed in yet. |
