Steiner Posted January 8, 2018 Report Share Posted January 8, 2018 I have a 2008 rev 4t with a broken kickstarter pinion gear. I need a replacement or a cad 3d drawing to build a new on. Any help on this fix would be appreciated. See pic of broken gear and gear with broken tooth. Thanks, Steiner Quote Link to comment Share on other sites More sharing options...
copemech Posted January 8, 2018 Report Share Posted January 8, 2018 have you tried your beta dealer? 1 Quote Link to comment Share on other sites More sharing options...
dadof2 Posted January 8, 2018 Report Share Posted January 8, 2018 I would not copy that design even if I had a CAD drawing. There is too much unsupported length under the teeth, no surprise it has broken. Quote Link to comment Share on other sites More sharing options...

I just found out BETA has discontinued the part and has an upgraded part with one other gear and shaft for twice the price. Quote Link to comment Share on other sites More sharing options...
lineaway Posted January 9, 2018 Report Share Posted January 9, 2018 10 year old part breaks and the complaint is they upgraded the parts. 2 Quote Link to comment Share on other sites More sharing options...

Steiner Posted January 9, 2018 Author Report Share Posted January 9, 2018 Beta discontinued the part. I cannot order it anywhere. They are in the process of making a replacement, but nothing is completed. Meanwhile my bike is useless. I choose to finish the work myself, and yes it will cost more but I can always sell some on eBay. Once I have the plans and mold I can make an unlimited number. Made these bikes in a month. 08 Honda CRF 250 frame with a CR 500 aluminum frame and a KTM xc450 frame with a CR 500 motor. Quote Link to comment Share on other sites More sharing options...
Steiner Posted January 9, 2018 Author Report Share Posted January 9, 2018 the ten year old part has been replaced five times, yes five times.. That is a poor design! My Gasgas (99) does not have issues. I have multiple bikes and non of the other ones have problems. This part sucks. Beta needs to step it up. I will dump this machine once its fixed, never to buy this brand again. To many other machines without problems. Quote Link to comment Share on other sites More sharing options...
trapezeartist Posted January 9, 2018 Report Share Posted January 9, 2018 Every bike has a weak spot. Personal experience is a more measure of the reliability/durability of anything as complicated as a motorbike. If a particular item has a 10% failure rate, 90% of owners will have no problem and say the part is good. The other 10% will think the item is rubbish. Making wild generalisations on such a small sample size will not get you far. On the other hand, I once owned a Hillman Imp for a short while (yeah, I know!). That car worked it's way through every problem the Imp was know for, and then started making up new ones itself. Quote Link to comment Share on other sites More sharing options...

You are way off the mark if you think other makes are in general more reliable than beta. Quote Link to comment Share on other sites More sharing options...
pauls320 Posted January 9, 2018 Report Share Posted January 9, 2018 Maybe you can shoehorn a cr500 motor into the Rev4 frame....then your off to the races Quote Link to comment Share on other sites More sharing options...
Steiner Posted January 9, 2018 Author Report Share Posted January 9, 2018 I thought about that but then I would have to change the tranny and the motor would be to heavy. Quote Link to comment Share on other sites More sharing options...
Steiner Posted January 9, 2018 Author Report Share Posted January 9, 2018 just trying to get some discussion going. I like my Beta, just cannot believe the effort they put into this particular part. Gears have been around along time in motorbikes and should not break like this. Just another problem to solve. i am trying to make this bike better, but in the future I will do much research on problems with bikes before I buy. This particular year of Beta is the issue. Just making a statement on my dislike and bad taste, did not mean to offend. I love your Beta as much as you. Quote Link to comment Share on other sites More sharing options...
pauls320 Posted January 9, 2018 Report Share Posted January 9, 2018 Lots of Beta owners around here and several Rev4s now and past, never heard of issues like this. Just a thought here, no offence or finger pointing intended: Do you stab at your kick lever before letting them ''Mesh together'' completely? This method is big killer of any kickstart assembly, especially the cogs in a light weight trials motor. Hope you can get sorted soon and back on the pegs. 1 Quote Link to comment Share on other sites More sharing options...
Steiner Posted January 10, 2018 Author Report Share Posted January 10, 2018 Paul, thanks for the tip. I try not to kick the bike like my 500, but who knows. I have four boys riding it so between all of us, I am sure someone or all kick it to hard. The gentleman I purchased the bike from had three broken gears and this is my first. Bottom line is the gear is a poor design. I will work on making it better. I really, really like the bike, just disgusted with these gears. This is just another problem to solve. This particular year of Beta is the issue. Just making a statement on my dislike and bad taste, did not mean to offend. Tim p, I love your Beta as much as you. Frustrated not being able to ride.
