Need some input

Ok guys here we go. finished my 1st build yesterday. took her out this morning, no problem. took it out just this afternoon, the chain idler pulled in when I engaged the engine (I have it as tight as I can get it on the tube) and the chain jumped to the inside of the sprocket and snapped off my master link...thank god that's all that happened. is this idler worth the risk or is it advantageous to fab one that goes between the two bars supporting the back of the bike. I just don't like the way this idler pulled into the tire like it did. I thought the chain was straight as I had no problems this morning. I am looking for thoughts of those who are more experienced than I at this. Thanks guys

The universal bracket that the idler is on is a joke, since most chain stays will be a different diameter. Most people drill and tap a small screw through the idler bracket. Myself I have never used one of the kit idlers. I machine my own bracket and idler.

Most of us who run the tensioner will use a small sheet metal screw or something to keep the tensioner from twisting.

You can run without the tensioner but I like to use mine.

When I felt that chain jump, I thought the pooch had been screwed. thank god only the link busted. Is running the idler closer to the sprocket an ideal placement or in the middle somewhere? I saw on here one of the guys gave instructions how to make an idler that looked pretty good, was gonna give it a try but I lost the link to the instructions for it.

use high temp gasket material it is suprising but when compressed between the idler and frame that tesioner will not move shaka

I may give that a shot. Can i get another master link for the 415 chain at TSC or will I have to go to a small engine shop?

[motovation man]

you can get masterlinks at napa better yet get a chain break shaka

thats a good question and i think i may have an answer i went to ace hardware and foun a 415 master link for 2.00 i think most of your hardware shops should have them but not home depot or lowes hope i could help maybe try gasbike.net there the cheapest i know of thats where i buy all my parts good shipping also real fast they ship the next day good luck have fun

If your local Ace doesn't have them you can always order them from most of the numerous online dealers. Dax carries them and they are good people to deal with. You can also use #41 Roller chain if you find a supplier nearby.

I will try Napa and ACE. the Hank across the street doesn't carry this chain, course I live in the town time forgot too. A chain breaker would be NICE. so much easier than grinding the pins off and popping with a hammer.
