The tint does look a little different then the mix they did for me using the same number. Here is my current project I just finished painting using the same paint I used on my RZ.

Regards Robert

Could I ask where you got those graphics? I'd like to do something similar on my race bike.

Thanks!

garys production costs are probably.. more overall, I cant imagine what his rent is. he is a one man show. currently owning both pipes, i can say the specIIs are damn good as we all know, and the jls are as well, just a preference.   the specII's are def racier and tune differently than the lomas pipes.

Not looking to start any fights but a pretty well known east coast builder/tuner called the JL pipes "noisemakers" whenI was in his shop dyno'ing a bike with a friend not too long ago

I went through this a year ago, looking for pipes for my RD350. Milleniums became unavailable (again), I went around and around with Chris at Patriot, Dogster wasn't around yet, there were lovely but unavailable pipes out of the Czech Republic and shiny things from India with unknown performance, quality or actual availability. It came down to price and availability: Spec II were more money and I'd get them someday, while JL were in stock at Economy cycle. Done.

Are Spec IIs really more than JL pipes these days?

A very well known racer that I race with in AHRMA had very nice things to say about them (even as compared to a stock Daytona head cut but Scott Clough). Haven't heard any feedback on the non-race version.

Just FYI Motolanna swingarms are back in stock - just ordered one for my race bike: https://www.motolanna.com/ourshop/prod_448876-Swingarm-Aluminum-Alloy-SuperTuff.html

Just to be clear, those are both analogue systems as far as I can tell and are not programmable.  The "curve" is a function of component choices in the design and can't be modified or programmed.

That 'curve" is basically the same as an older Motoplat or HPI or PVL.  If you want to program more advance at lower revs or more retard at the top end, after peak power, those are not the ignitions you are looking.

Maybe once I'm a frontrunning racer! As it stands, I'm aware of several folks getting good, usable power from PVL setups and whatever timing curve is inherent to them. Given that the VAPE unit is similar (which I learned in this thread - thanks, guys!), I'm going to slap it on and run it/not worry about it for now.

I do hope to put my bike on Ed Toomey's dyno once it's done. I'll report back on power numbers with cylinders & heads given the full Scott Clough treatment, VM36s with big vForce reeds, VAPE racing ignition, and Swarbrick pipes if anyone is curious?

They list this as the curve:

for this system

easiest way to know is to throw a timing light on it, make a timing pointer and watch it as it revs.. but i assume you motor is apart.

if not, then HPI system has a curve. However, you can always email vape and ask if your system does.. but they advertise it as such.

This is exactly what I was looking for but failing to find. Looks like my system has about the same capabilities as the PVL (plus i don't need to weld on an additional bracket to hang a second coil).

Thanks very much, guys. Knew I could count on the wealth of knowledge here.

Mark, the motor is shockingly back together well in advance of the first race of next season, I just need to sort basically everything else out. I'll throw a timing light at it when I get her running and report back.

Hi All,

Want to validate something that I heard before I spend any more money on the race bike...

A little background: I have been running a total loss Vape/Powerdynamo racing ignition on my AHRMA bike for several seasons now and it has performed flawlessly. I recently decided to change classes and rebuild the bike for considerably more horsepower (moving from mid-30s to mid-60s).

My porting guy asked if my ignition had static timing or operated on an ignition curve. I believe that I read that the Vape units are static so have been eying the PVL units. Problem is - I can't find any solid info as to whether either system has static or dynamic timing. Can someone more knowledgable weigh in here?

Thanks!

$880 USD...It's a very nice piece, and I understand structurally superior to the aluminum Motolana 'arm I bought. But I could have almost gotten two Motolanas for that price.

Except the Motolana has been out of stock for months and this is made in the US!

Nice, what is he selling them for?

+1!

You racing with AHRMA or a different org? Formula 750 being the featured vintage class next year is going to be a lot of fun - should be a lot of fast riders on fast 2 strokes on the grid.

I had had my eye on these when they were first listed on Economy. Not to steal anyone's thunder but I think I'll be mounting a set of these to my race bike instead: https://vintageperformanceproducts.com/shop/ols/products/yamaha-rd400-billet-heads

I bought this + a Mead Speed windscreen from a fellow racer for $325, which seemed like a pretty sweet deal vs. glass from the past + gustaffson.

I haven't mounted this at all currently. It's just sitting there so I could eyeball it. I'm thinking I'll make a hollow tube on the lathe to weld to the headstock of the frame and thread a grub screw into the end. I'll fab up an aluminum fairing stay that slides into that. For mounting the upper corners I'm going to stick a heim joint to the crown nut on the top triple and run a rod through it and yes, I'll weld some tabs onto the frame to mount the lower wings.

Happy to post more pictures as things progress if y'all are interested.

Once you get a windscreen on it, that'll be perfect.  I  love the vintage road race look!  Nothing better!

It's a dedicated race bike so might as well make it look like one!

Re-doing the race bike at the moment and giving some thought to the bodywork. I was thinking that this dunstall upper fairing would look all wrong with the TD2 bodywork (TZ-style tank), but the initial mockup actually looks.... pretty awesome to me. What does the hive mind think?
