changes in engine power

Today at exactly 12 noon, I arrived at a crf motorbike with a 160cc up-drill engine with an offroad style, this motorbike that I previously modified from the parts, the drilling machine for up touring 160cc, my product body trotol using BRT, custom offroad rear suspension, suspension In front I replaced the inner tube and adjusted the oil shock, I replaced the ignition with KLX's standard Akrapovic exhaust, I adjusted it to the engine specs.

First I made changes to the rear wheel, from the start this motorbike used a 150-wide wheel. Ring 17. Then I changed it to 250. Ring 17 tires I used the corsa brand size 300 17 at a price of 550 thousand and the drum bearing part I used the FAG brand with a unit price of 125 thousand because on the drum there are two bearings, which is certain I have to match the two with the price of 2 250 parts, then in the boss section I use the standard shock because it lasts longer at a price of 150 thousand.

Then I also made changes in the front and rear gear, the standard size of the front gear is 15 rear eyes, 49 eyes, of course with the standard gaer size, if you use touring, it's certain to vibrate at the top RPM because this motorbike is designed for offroad, and I immediately replace it. with the size of the front 17 rear eyes 47 eyes with the Daytona brand at a price of 580000, my chain uses the SSS brand at a price of 250000

And on the rear drum because I use a gaer that's too small, I'm sure if I don't customize the drum, it's clear that the chain will rub against the drum and I have to cut the drum because the chain and gear I bought is separate, it's clear we have to buy a more chain long, because the chain is long, I definitely have to cut one so that the chain is not too loose and easy to adjust according to usage, it's not up to here friends, the rocker arm bearings also have to be custom made with used car tires.
