Canadianshee Posted April 27, 2017 Report Share Posted April 27, 2017 Here's the 97. Nice score. Have always had a soft spot for this colour scheme. Sent from my LG-H831 using Tapatalk 1 Quote Link to comment Share on other sites More sharing options...
Strm Trpr Posted April 29, 2017 Author Report Share Posted April 29, 2017 So, I got an update. Pulled the motor and tore it down. STD bore wiseco pistons in a 97... weird. Found a broken left exhaust side piston skirt. Big end rod bearing is wasted. Shrapnel within. Split the cases, all is good. Transmission is completely perfect. Shift forks have absolutely no signs of wear. Here's the plan. Cases, virgin cylinders and the Mull pump gas head I have are going to Don Shepherd at Powerline Performance up in Woodland, WA for a stock stroke dune port. Stock stroke hot rods crank from Jeff at FAST is shipping directly to Don. Jeff trues/welds these in house, so they're perfect. Transmission is going to Joe Molinari for a pro mod. $300 return shipped for the pro mod with the drum bearing mod, detent arm bearing mod and modded shift star. Joe claims a 3-5 day turnaround from the day he receives the trans. Not too shabby. Today the man in brown delivered a much needed new pair of Alpinestars Tech 5's and new riding pants/jersey. Also on the porch was a new set of 21x12x8, 8 paddle extremes. I'm super stoked, because in exactly 4 weeks from today I'll be running this new Powerline stock stroke dune port in my blue 2002 shown above.

As eager as you are to ride make sure your jetting is in check. If your not sure start fat and work your way down. Check plugs Ect. Too many people just install and ride without the proper jetting as you may already know and grenade the motor. Quote Link to comment Share on other sites More sharing options...
Strm Trpr Posted April 29, 2017 Author Report Share Posted April 29, 2017 Yes, thank you for the reminder. Jetting is very important. I do all my tuning. I have a digital tach and a FAST sync tool and a bunch of jets. Thankfully my buddy lives in the country and we have room to tune. I do proper plug chops. Plugs are cheaper than pistons. Don said when I get the motor back I'll get a spec sheet with all of the vital engine build/porting specs and suggested jetting. I haven't been on the sand since memorial weekend of 2016...

gusto Posted April 29, 2017 Report Share Posted April 29, 2017 I got to ask. For $40 more you'd have a striker crank, so why not? Also why not save money and rebuild stock? Regardless sweet build Quote Link to comment Share on other sites More sharing options...
RagunCajun Posted April 29, 2017 Report Share Posted April 29, 2017 What digital tach are you using? I'd like to hook one up with a visible needle but I'm not sure how Quote Link to comment Share on other sites More sharing options...

Regardless sweet build All good questions and my buddy and I discussed all of them except rebuilding the stock crank.1) Don told me rebuilding, trueing and welding a stock crank with parts/labor is damn near the price of a new one. 2) the reason I'm not building a 4mil stroker is because this motor is going in the 97 for my sons to ride. They've only ever ridden a POS 125cc farmer john rental quad at Pismo back in 2011. So in short, a 4 mil stroker would be a bit much for a couple teenagers to learn on. 3) Cam @ Redline is building me a MX ported 421 Serval for my blue 2002, but it is not going to be ready for memorial weekend 2017, so this motor is going in the 2002 to get me through the weekend. What digital tach are you using? I'd like to hook one up with a visible needle but I'm not sure howI have just a POS electronic eBay tach for tuning only.I found this on you tube and it's a 2 stroke. https://youtu.be/lSG-325gNic 1 Quote Link to comment Share on other sites More sharing options...
RagunCajun Posted April 29, 2017 Report Share Posted April 29, 2017 Got a graph of his mx port work? I want to see the curve Quote Link to comment Share on other sites More sharing options...
Strm Trpr Posted April 29, 2017 Author Report Share Posted April 29, 2017 No, it's at Redline now. All the same parts as this build but with less compression and timing for pump gas. http://www.bansheehq.com/forums/index.php?/topic/185991-redline-4mil-serval/ Quote Link to comment Share on other sites More sharing options...
Strm Trpr Posted May 6, 2017 Author Report Share Posted May 6, 2017 Joe Molinari is outstanding! His customer service is second to none! If you're in the market for any custom transmission work, do not hesitate to contact Joe at Joe's ATV Performance and Fabrication on Facebook. He's even drop shipping the transmission to Don at Powerline! Quote Link to comment Share on other sites More sharing options...
