Locked up Tranny? What to mod

[Dog86]

Last year my banshee's Drain plug came out and ran the tranny/cluch dry and It locked up the tranny. It would run real good just would not move at all and I fried the clutch trying to make it move. I split the cases and the cluth was fried but I couldn't find anythin else wrong with it the gears they looked perfect.I cleand up all the cluth pieces and I spun the gears and they move freely now that it is apart and they shift fine. The shift forks look like they may have got hot and look discolored. I have a set of fork to put in it just wondering if It world be something else. Also the gears that are in it are from a newer banshee because it would kick out of second gear with the other gears that were it it. I put the newer gear pack in and It worked for 6 month or so until the drain plug fell out.

 

It has been sitting in the barn for a year now I figured I I had better fix it now that I got my raptor running. Also what should I do to this old beast. It have a few mods done to it I'll list below. It is a 87-88 I'm not sure yet but The motor has low hours on the pisons-rings with a fresh bore about 6 hrs ride time on them so I would like to keep the pistons and stuff like that for now and not buy new ones. It has a stock crank Cool head with 19CC domes FMF Pipes Not sure what series they are they say (FEEL THE POWER) They don't have any other marking on them. Any one know what they are. It could use some new reeds Im sure Thay have been the same for the last 10 years lol. I have the J-arm to A-arm Conversion with +2 A-arms And works Triples with Rez. I need a new rear shock. But A stock one works for me as I don't jump just ride around a field and the dunes. Other then that what should I mod. I have tires and stuff like that but what are the good bolt ons.

first thing i would do is find exactly what was binding on them. it could have been the forks not sliding on the shafta and making it catch 2 gears or something, or in the durum, or locked up bearing......the output bearing, or clutch basket bushing, mabey even the rear axle? some tranny mods may be nice, like having every other dog cut on the gears, having the drum cut for a bearing, shift shaft, billet impellar, anything with the clutch, especially a pancake bearing. porting would be really nice to get now, and you don't have to bore/hone/ring, if it's all still good. you can have the cyls just ported. other than that, there is tons you can do outside of the internals, and still more inside, depending on your needs and budget.....what kind of ridding and conditions? how much are you willing to dish out? some pics of the pipes would be really helpfull to id them......they will be mid-top pipes, or woods pipes from the early 90's if they don't say gold series, or any class, like fattie, gnarly, etc. is there a signiature on them?

I found that the 5th gear pinion welded it self to the shaft. Took me a bit to find it because I though the shaft was splined for it but it was supposed to spin lol. Thankfully I had a spare tranny that the 2nd gear was bad on so I made one good tranny.

I'll try to get pics of the pipes up tomorrow. Never posted a pic but I will figure it out.

 

What is a pancake bearing do? I'll be pulling the motor apart this winter and putting a +4mil stroker in it and get the cylinders ported so I will hold off on the internals. Don't have a ton of cash now. I modded the shift star today and will mod the shaft tomorrow. any other things I should grind on tomorrow lol. Also what is the best impeller to buy my buddy bought a modquad and had nothing but problems with it. He said it wouldn't fit right.

 

I Thanks for all the help

Pan cake bearings prevent welding the ball to the rod that disengauges the clutch. When that happens, sometimes you have to Split the cases.

depending on what kind of ridding you do, and tooling, you can cut every-other dog off a few of the gears for better engagement chances, to lessen mised shifts and shorter times. best ompellar i've seen, hands down, is the mull press-on high flow. you use your stock shaft. for some reason, the aftermarket shafts just don't hold up as long as the stocker. what part wouldn't fit right on the modquad impellar?

[Dog86]

He said it was the shaft was to big but that was 3 years ago. I never seemed to have a problem missing gears so I didn't grind any of the gear mostly because I wanna get it running today lol. I ride mostly fields and a small gravel pit and the dunes a few times a year. Don't do much drag racing with it cuz I have no fast quads to race with except for mine and a couple YFZ's nothing fast enough to hang though.
