Need help Tecate guys. PVL ignition on my T3? What is it?

[Hoosier_Daddy]

flywheel mass has no affect on rpm potential.. if there is an rpm gain its from changes in the timing or strength of the spark. I personally wouldn't touch a pvl if I planned to ride on any surface other than sand...

I noticed in an old thread you said going from a Tecate to KX ignition reduces traction and a PVL is probably worse. What did you mean by that? You mean low end power? Worse hole shots?

90% of my riding is done on open trails and open fields. I'm not going to MX my T3, and if I ever get into some wooded trails it will be few and far between. I'm trying to restore it to be nice but usable. I don't want to dump all my time and money into it and go beat the living crap out of it and destroy it because i don't have the time or money to fix it back up. But at the same time, I do want to go riding it and enjoy it.

Everyone I know that is building a tecate to be reliable and fast has the pvl ignition on there list of must haves. I know I do. I'm sure you'd have no problem selling it. I have a brand new ricky flywheel (never ran), with good oem stators coil cdi, plus a box full of stators, lighting coils and a couple cdi and coils I'd trade for what you have. If I were you I'd keep it though.

What people are talking about with the kx or pvl vs the oem or ricky flywheel, is mostly holeshot and some low end diffrences. It is like putting a lightened flywheel in a car, revs easier and faster, but the holeshot and hard shifts suffer.

Imagine your t3 motor running. With the stock or ricky flywheel your turning 3-4 lbs of weight (duno exact numbers sorry BUT the ricky is heavier than stock!). Now imagine what happens when you really snap the clutch. It will really drag down the motor. With the extra weight already spinning it is easier to turn the drivetrain. With no weight it is alot harder to turn the weight so it can bog the motor down alot easier. So it will be really finikey to start and may bog more on wot shifts. In turn, when the motor is revving, the less weight is has to spin the better. So with a lighter than stock fly you can spin up faster (not higher, that depends on alot of other things!).

I hope you can understand that, easy concept just hard to explain.

Since all the tecate guys are reading this anyone have a good 84-85 jug and or piston? I have 2 tecates sitting with toasted top ends. pm me if you do!

I meant that traction was worse with a lighter flywheel. power delivery becomes abrupt... More difficult to adjust, more difficult to start, easier to stall, harder to find traction... Sure the throttle response is greatly improved increased and the bike feels faster because its less controlable, but in reality zero more hp are getting to the rear wheels... All I know is that on short wheelie happy green trike with a hard hitting powerband and a grabby clutch the last thing I would ever buy or use is a pvl.. although it would probably work good for scaring my friends and impressing my internet buddies though..

A PVL is on my "to do" list, for many of the reasons cr480r listed.

I personally like a lighter flywheel on machines 250-up, but then I don't ride a 2-stroke chugging around through the woods or over slow/rough terrain.

I had a '92 KX250 earlier this year that had a Stealhly flywheel weight bolted on it. All the woods/enduro type guys praise them and swear that heavier is the way to go. I tried it both ways and the weight came off and got sold. I like my flywheels on a diet, my power abrupt, and my engine to spin up quick.

I agree 100% To me a pvl would be perfect for oval ice racing. Where engine speed is kept high the whole time, and smooth power matters little. For trail and general riding weight in the fly is your friend. It becomes verry difficult to launch a bike with little mass, unless you have geared way down. Then this creates a whole new problem. The engines ability to handle and make power at elevated engine speed, to compensate for shorter gearing.

You can buy PVL flywheel weights. Will the weights fit in the stock cover? Probably.

PVL sells a puller too but it looks like you can use an automotive one?

I was able to take it off with a regular puller so it wasn't too bad.




To the other guys, like I said earlier, most of my riding is just open trails and fields. I won't be worried about launching for a drag race but i don't want the revs to be so uncontrollable that it won't be fun either. I'm running an 86 swinger which gives me 2" over stock and I am not interested in extending the swingarm any more because i want to be able to ride it around and have handling. I'm not building a drag racer. So i don't want this ignition to make my powerband hit so hard and fast that i can't gun it without fear of a flipping it over wheelie. Now, I'm confused if this would be a good setup for me.

I'd suggest just running it then make your decision. I'm sure it's not going to make the bike un-rideable and I'm sure you will like it just fine. I'm sure it makes a difference but it's just ignition, it's not like you are putting a CR500 engine in an ATC70.

its still a 250 so its not gonna completely try to kill you...lol.. but it will come up and over faster when it does find traction.. I took a mere 5oz off my quadracer flywheel and it completely changed the bike.. It was was much snappier(i liked it at first), but the tires always felt bald, the rear brake would kill the motor easily, it stalled easily in technical stuff and required alot more clutch abuse, and i even noticed it being less forgiving when jumping... and I damn sure didnt have the talent to ride nice wheelies on the beast anymore... 5.5oz off a q-racer flywheel is not near as much of a change as the kxt to kx swap.. and not even close to the difference between kxt and pvl...

on my tecate i am running a '91 KDX ignition that is heavier than the KXT... throttle response is not a problem...the motor is snappy enough and very controlable..

You can buy PVL flywheel weights.

I have seen those, it seems to me like that could potentially cause problems with the timing staying where its put... I dont like the idea of not having a key in conjuntion with flywheel weights
