Starter chain guide set 139FMB 4T

Hello I own a junak 901 with a capacity of 50/70cmm from new purchased in 2011 to date Junak has traveled nearly 17 thousand km What I really like about the moped is the simplicity of the whole motorcycle, there is nothing complicated in the repair process, simple design, availability of parts is huge and easy to obtain. This is the second repair of the engine since new due to the fact that I ride a lot, parts wear out, now I have overhauled the engine again and the motor fires up from a shot, the larger gear ratio gears allowed to run longer in gear and achieve better results speed in km ends as soon as the pointer passes 80 I like to test various products with them especially carburetors and filters to get better results in combustion and on power of course it is possible but several carburetors of different manufacturers of fuel nozzles you need to have to get such an effect . Parts from gmoto I buy because it is a proven seller of parts and really parts are of very good quality than on other sites only now what I bought starter chain sliders significantly differ from the original I would say more that the quality and material are other weaker but for everything there is a way site I recommend to all lovers of unicycles

Rocker Arm with Base GY6 50CC

Router deluxe 1 50 At first glance solid however when you install Does not fit the bottom valve(does not go to ease the slack) after lightly tightening it has already broken, even more than the previous one, the product is not suitable at all, I definitely do not recommend this product Terribly soft

Timing chain 82 links 4T 139FMB

Timing chain for junk, of course, as for me a very good quality I compared with another chain purchased and the bending of the chain is greater evidenced by a different metal alloy which will cause stretching faster at a later time

Timing chain guide roller 4T 139FMB

There are hard and soft rollers, I personally prefer the soft one because the roller works in extreme conditions of temperature and oil hardens over time and can crack or there is a breakage of a part, therefore I choose the soft material
