timing keys?

[finsteratv]

i know a timing key commonly the sparks key is used to advance timing. i also noticed that wheelie on here machines some. while looking at keys ive seen how much it advances the timing +4,+6 and on and on.im just wondering which gives you the best gains on a sock motor and the differences between keys? sorry about the long post haha:p

sparks key is +6 and use on anything with a compression ration of 10:1 or lower.

Where you run into trouble and why wheelie makes other versions is if you have an 11:1 or 12:1 piston. The timing advance with as sparks key causes to much heat and thus you need something lesser.

wheelie on here makes the 3 and 4 degree keys.

sparks makes the 6 degree.

I second marcs comment on the 10:1. 11:1 is good with the 3 degree though in some cases. I will be testing it a bit more this spring with both the 3 and 6 just to see how it does.

most of the time if you want to run 11:1 and a 6 you would have to run 110 octane or other race gas.

haha alright thanks guys just "learning"my keys and the applications for them :p

no problem. it all depends on the setup really. I feel it is more of a top end type of mod along with a bit bette throttle response throughout. the 3 is more mid compared to the 6. the stocker is more low than the 3. the 3 is a good all around one imo with a 10:1 setup. I have it currently with mine and like it alot. I think i will probably leave it in when i do my 440 this spring and see how it does on 91 or 93 octane. im keeping my fingers crossed cause i dont wanna buy race gas for it. I will put the stocker back in before i do that.

Ive been tossing a +3 key around for a longtime now, I just fear Ill need to run 100 octane or better for it and that is not cheap. I tend to run thru a tank in about 6-8 hours of hard riding and it gets costly.

For a stock engine or one with 10:1 compression its a great modification and well worth the time and cost to do it.

[honda400ex2003]

both are great with the 10:1 or under. I like the 6 for a drag race style setup, the 3 for more of an mx style setup.

marc, give one a shot. If i didnt have it in my machine i would send mine to you to try out for a bit to see if you like it. maybe wait till spring and ill see what i can do for ya in that department, then if you like it, just buy one and send mine back.

I was thinking about doing it this summer steve, but really want to throw on some +2 arms among other stuff too (more $$$ lol). I also need to retune the carb, it def is not correct-but close, probably need to go up one jet size.

Just got my new razr2 fronts today I gotta get mounted and waiting on my new 39t rear.

Planning on it, just need some more cash. Although since I have some rather new kenda klaws on the rear I might wear them out first.

Im def doing some JD performance arms when I get the cash. The max ground clearance type should work awesome.

[honda400ex2003]

def, they are on the proposed list of stuff to do to the 400 this summer too. lol maybe not though depending on if i work or not.

I wanna get the 250r restored first instead. I have to get fenders and stuff for it before getting parts for the 400. steve

I would really look to do it to match the g-force +4 axle I got when I bought the quad. Its kinda off balance right now with that and a stock front.

Might make riding the trails a bit harder, but if the rear fit thru everything Im sure it will be fine.

I wish I had a 250r just to be different sometimes, 4 strokes fun but a 2 stroke is just a whole different ride.

[honda400ex2003]

i dont really get too excited about the r to tell you the truth. i got a good deal on it and wanted to restore it. thats all. once i get done with it, it will probably sit alot. i will drain the gas out and run wd-40 through it most likely and let it sit in the garage. esp when i get my own garage. it will be the start of my collection i wanna have. steve

See, I would have trouble deciding what to take with me when I go riding :D

[honda400ex2003]

yeah as the r developes a bit more it could be troublesome i suppose. i still love the torque of the hundy better though. takes alot more work to ride the r fast. lol im not always wanting to ride like a mad man to keep it fun. wheelies are much more fun. :devil: i have about 1200 bucks worth of stuff to get for the r this summer to finish it up. plus a few other things that i want to try to find to finish it off from Dennis kirk and make it complete such as graphics and such. that is with a new chain, sprockets, all new fenders, bars, tires, and rims. I have to get one of the oem air deflectors for the front also but they are hard to find. I have the rest of the stuff already, i just have to bolt it on. steve
