Maybe two weeks ago I got my Tecate going again and took it for a ride. Found out quickly that the carb is still not set up right. So pi**ed off as I am I decided to let it sit on the backburner for a few months.
I've now began work on my ski-doo, a 1990 Yamaha Bravo short track.
It has been mine since last winter, since I've got it I've replaced some broken parts and put it through hell and back and it still runs like a clock. Problem is the front suspension pivot. The bolts are ripping sheetmetal. Its fixable but I decided a replacement body would be more fun to work with. List of planned mods.
1) The bodies on these machines are pop riveted together and abuse can lead to major breakage so I'm going to weld the entire body solid to strenghten it.
2)The body will have a thick plastic bellypan to keep it from lookin like the one on it now.
3) The floorboards, they always bottom out in deep snow and get you stuck. Going to cut and reshape them and add minipegs to brace them keeping them from flexing.
4) Using heavy duty skis from a Bravo Transporter for durability.
5) Raising the rear ride height for ground clearance and using a gas shock instead of the crap hyraulic piece.
6) Cutting the back half of the seat foam off for weight savings and using the exposed deck for a snowboard/gas can rack.
7) Removing the premix system for weight and because I dont trust it.
8) Making some control changes like one switch for lights/kill.
9) Cutting my stock Tecate pipe and making it fit. Puttin a drag pipe style silencer on it. (BRAAAaaaap!!!)
10) Using my Tecate carb on the sled motor. From like a 28 to a 34mm...maybe too big.
11) Maybe an Enticer 300 swap. If not then I will go with a Wiseco piston and some polish work to make sure everything flows 100% the way it should.
12) Uncluttering the engine bay to make its clean and functional. No unnessary wiring or plastic covers, general cleanup for weight savings.
13) Shaving off the rear tail light housing.
14) One tooth bigger on the bottom gear to get some more bottom end.
15) No windshield, red Powermadd hand guards and 45/90 degree bar ends.
16) Clamp on UNI snow filter and junked airbox housing.
17) Bigger drive belt from a 340 Enticer.
Should be started on this project by the wkend, first I'll complete all the body mods. Buying an 89 Bravo shorttrack in great condition for $300, gettin what I need and parting what I can. This skidoo will be built to climb, bust powder and rule the tight trails around here (well rule when I'm riding with more Bravo's and the like). Its always been a capable machine and gets me where ever I point it, I'm just making it better and totally original. Hope everything works the way I want it. Only mod so far is some BMX bike handlebars that replaced my toasted originals.
Heres a pic of what I'm working with in case some of you don't know what a Bravo is.
