okbeast Posted October 9, 2006 Report Posted October 9, 2006 Like the topic says, I was at the dunes yesterday doing some dragging and it seemed when I hit the top of 5th gear it would start to bog. It was no more then a month ago that I was riding in the sand, complete same setup except I went up 1 tooth on my rear sprocket, and while drag racing didn't have any bogging. I did go to a slightly smaller K&N pod setup but wouldn't think that would affect it. It runs very strong in all the other gears and doesn't cut out. I was thinking maybe jetting was too rich but shouldn't it affect all the gears? Quote
dajogejr Posted October 9, 2006 Report Posted October 9, 2006 What do your plugs look like? Do a plug chop... http://www.dfn.com/benkaren/plugchop.html If the plugs turn out fine, I'd bet you don't have enough motor to pull 5th or 6th... Sand robs power big time, I'd bet the last time you ran it...it was wet or hard packed sand.... One tooth larger in the rear should HELP you pull a bigger gear if anything...I'd bet it's either rich...or, you don't have the motor. Did you check the paddle pressure, to make sure they had enough air in 'em? I normally run 4PSI. Quote
okbeast Posted October 10, 2006 Author Report Posted October 10, 2006 I do need to do a plug chop just to see where I'm at there. I was running about 5 psi this time while running but last month I was only running 2 1/2 psi and both were on pretty soft sand. On this most recent trip the sand was alot more wind-blown so I bet it was softer and just robbing that little bit of power. I have a timing plate and milled head on the way so maybe that'll give me that little bit back that I'm missin. I was also running some sand-skate II v-blades and they did good in the trails and turning and on the dunes but for the dragging I was just spinnin the shit out of them. What size haulers or other tire would be good? I was thinking a 20x10x8 8 or 10 paddle hauler? Quote
dajogejr Posted October 10, 2006 Report Posted October 10, 2006 What are ALL your mods? What about swingarm, stock? Quote
rocketboy Posted October 10, 2006 Report Posted October 10, 2006 as long as the jetting looks good ..it sounds like your reaching the limitations of your port configuration ,in other words you need more power to prevent bogging in the high gears .alot of people who ride dunes tend to say 10 paddle haulers are better suited for atleast 60 hp and up Quote
okbeast Posted October 10, 2006 Author Report Posted October 10, 2006 (edited) I've got dual K&N's, T-5's, and some FMF reeds (that's what the guy told me I got them from), 13t up front and 42t out back, will have timing plate and .30 over milled head. Carbs are stock, swinger is stock. Edited October 10, 2006 by okbeast Quote

Definately 8 paddle you like to pla around but I'd solve your gearing problem switching to haulers is going to make it even harder to turn the tires.. But it also depends on swingarm size, (longer = more padles_ HP, sand density riders weight etc... *you have some pretty low gearing, so I'm not sure why your having poblems in those gears. I'd stick with skates until your ported your not going to be winning any drags anyways Edited October 10, 2006 by Justintoxicated Quote
okbeast Posted October 10, 2006 Author Report Posted October 10, 2006 Yeah I plan on doin a rebuild/port job sometime over Christmas break most likely. My buddy had his banshee out there w/ the same mods as mine (he already has the timing plate and 19cc domes) and was outrunning 2 piped 700's and 1 yfz450 so I was fairly impressed with that. Quote
dajogejr Posted October 10, 2006 Report Posted October 10, 2006 was outrunning 2 piped 700's and 1 yfz450 so I was fairly impressed with that. He he.... Wait till you port it....whole new ball game. Quote
okbeast Posted October 10, 2006 Author Report Posted October 10, 2006 Yeah that's what I've heard. I figured I'd just get it ported while I had the head off for the rebuild. I live near KS too so I thought either F.A.S.T. would be good or Passion motors up in Tulsa. I'll still be running everything else stock just with a port (most likely dune port since that's really only when I'll be doing serious "drag racing"). Quote
