I now have two sets of gears to make a 74% and 82% for 300 BR/fourtrax if anybody is interested, i won’t make the GR as the cost of shipping isn’t worth while to me. DIY or send the parts off to be built.

I got these cheap ish so figured I’d offer them up on here.

I have to ask , what is the " BR " in the 300 BR/Fourtrax ------ very interesting parts , first time I ever seen something like a 74% and 82% gears go up for sale , too much reduction for me at the moment -----

 

[SamUK]

Haha.. Big Red...

74% is fairly popular now with 82 being called the ‘big GR’. I got them because the one gear can be awkward to find, there’s a good amount of metal to get a great weld on it you see. Figured somebody will want one soon enough.

not many over here call any trx300's '' big red '' ?..but I have seen a few of them around my area, they are very far and few of them in the states.

Yeah I forget that at times, Big Reds to you guys are 3 wheelers aren’t they.

 

[fishfiles]

Yes Big Red's are 3 wheelers , I seen the guys from Down Under have Big Red 4 wheelers

Sam , I was at Dick's yesterday and we were talking reduction on my 450 , I just realized that he might be interested in your gears , I seen some extreme machines over there yesterday , a Raptor racer with 1035 CC's and I watched the video of it making a run , I wouldn't want to be on it --------- if you want PM me with what exactly you have to sell and I will pass it on to him and maybe you'll can make a deal ----

I was always under the impression Dicks bought GR’s off Ron Shaw, I’d have thought he know some about the ‘big GR’s’ by now, he’s one of the main builders I thought.

 

[fishfiles]

He said that he did not need it , I thought by you saying one can be " awkward to find " that it could have been wanted ---------

 

[SamUK]

Ohh ok, I believe some builders use a narrow gear, about 1/2” wide across the teeth. These I have are 1 1/8” which allows for a better weld as you don’t weld into the gear mesh. The extra width on the teeth is then machined off to the desired size.

Reduction Guru - True or false ? TRX300 Fourtrax 54% = Bayou 220 pinion gear and ltz400 clutch gear

Not sure on the bayou primary but LTZ is correct for the basket gear. I used a Honda gear for the primary. I’ll find out the part number and post here for you. I wouldn’t post it usually but now the bigger GR’s are out I don’t think the 54’s are as secretive anymore, seems it’s pretty much common knowledge on bookface.

 

[SamUK]

Here you go @fiahfiles this is the gear for the primary... Or one of many you can use, obviously the pitch has to match the basket gear. Some builders use a wider gear and turn it down afterwards but it’s conpletely unnecessary, personally I believe they do that because they doubt their welds.

 

[fishfiles]

When you punch that number into Honda , these bikes come up :
Honda Motorcycle Models with no year CB200
Honda Motorcycle Models with no year CL200
Honda Motorcycle Models with no year CB200T
Honda Motorcycle 1976 CB200T

and that part number is no longer available , from what I have read , there must be other machines that use a primary that would work , my buddy has a Bayou 220 that is junk , that is why I am asking

 

[fishfiles]

I pulled up a pic of a Bayou 220 gear and it is bigger than the pic of the part number you listed , I see that part number you listed going as cheap as $6 ---I think there must be another gear out there that will work , as the list for that part number is small and kind of rare bikes , you would think with all the 54%s out there , the gears must be readily available ---- I seen where a guy was saying a Bayou 220 would work , but like I say from pics , I think it is much bigger a gear then the one you listed

 

[SamUK]

Yeah they are no longer available but I sourced mine from eBay. There’s usually quite a few available, it’s been a while since I sourced gears but as you say there’s lots that will do the job, if you get one tooth less than the one I listed that will give you 62% reduction using the LTZ basket gear. @mac102004 may have some other ideas as to sourcing gears.
