I runned a 885 10mm with this specs for the pump 12-17 c75 skat trak prop 86 nozzle but it was a bit underpropped so i think 13-19 c75 will bring you in the good range. For the flame i think 15 dg advance from 0-1200 29 dg advance from 1500-4500 and go in a straight line back to 14dg advance...

This is how i did mine 26 black pad bottom 26 black pad top and made foots with 8gray mm on top of the 26

Had my engine ordered at Thrust. Great custommer service and a real nice package. Had a damaged part by Fedex shipping they handled the box way to brutal. Made a call to Chris @ thrust and it was fixed imediatly and got a day later the tracking for the replacement part. THATS WHAT I CALL...

Found water in the hull so take all the foam out and made new footholds. Sold my old 885 10 mm dasa engine and ordered a new 10 mm 1100 @ Thrust. Pics of the engine will follow when it arrive

Powerfactor pipe makes this engine alive.

I reworked a stock 62t nozzle to 90 mm I.d and 94 mm steering. Cutted the nozzle and welded a 95x2,5 tube back to it so i.d is 90 mm and i can put rings in it to make it smaller if it is too big or bore it to 92 max

i do not agree this as the spring tension does tune the point the timing changes to higher dg op exhaust duration if this is to slow then it will stay in the "bottom end timing" to long. Is this to fast you come in the "top end timing" to soon. Just like normall porting a race ported cylinder...

Adjusting spring pressure can make your powerband better when they open to early the timing is high and cut of the botom end when they open too late it is like a lightswitch they keep closed to long and the engine timing is weak and then it opens and get everything. For my feeling it is a part...

I use heat resistant epoxy and mix it up with aluminium powder you need to let it cure 24 hr on room temp and then postcure it 15 hours @ 150 dg F after the postcure the resin is stable to 300 dg F with normall epoxy the resin will become soft @ higher case temperature. In the pic you can see...

I think a 9-18 in a 150 pump should be perfect. I ride a 885 10mm with a 148 pump and use a 11-18 and this one feels a little overpropped.

Damn thats a nice color/turf combo

Ok what do you use and what is the result ?

I got the boyesen setup complete and also have a set of v-force 3 reeds and cutted some spacers to put in the boyesen manifold so it is usable with the v-force3 also. I can test them back to back but i was exited if you guys tested them back to back and found some difference in performance.

What reed valves and intake should be the best/your choice and what are the pros and the cons about it My engine is DASA 885 10 mm Carbs is 49 full spectrum Msd tl Thanks

my vote is powerfactor

Damn you guys make it look so easy :bling:

I had a 781 dasa stock stroke pv engine with that engine i made the change from b-pipe to powerfactor and the gain was insane it felt like like adding a b-pipe from a stock exhaust. How does the riva dry pipe reacts vs the b-pipe ?

What bore your running ? I runned a 781 Stock stroke cast powervalve also with a PFP. Pump setup was 144 non setback solas mag with 12-17 c75 prop nozzle bored to 86 mm. Same jetting specs as my 10 mm 885. With this pump setting i switched to 10 mm 885 and it was really bad it only climbs fast...
