Good morning all. I picked up a complete 2001 cr igntion for my R, and an adapter plate from BDT. I think I would have preferred the ESR unit, but of course, not available. Has anyone used the BDT adapter, that could provide me with any pointers on installing this system? Is there a stock baseline timing mark to use? I haven't opened the side cover yet, just trying to gather info.
Thanks!

There was no installation instructions with the Big Dog Turd adapter?
-
No, but I did get a reply from them with instructions. Should be straight forward, but wanted clarification before I did it. Other than high prices, why does everyone have a negative view on BDT? Just curious. Seems to be the only company with any stock lately.

how did you find this site? you sure you dont want to be on .net and hang out with Maatus? LOL
carlos is a crook and got started on the forums acting like he was a customer of BDT instead of the shop owner promoting his business. He'll tell you need a new crank and piston, then put your old parts in someone elses motor build.
he has numerous alts to this day still doing that crap - pretending to be his customer
he claims stuff is new old stock, when its really used and he cleaned it up/restored it

I would also like to add that this site was created for the 250R enthusiasts that were tired of all the bs drama Carla created on .net.

this is at least forum #2 and maybe even fourm #3 to try to get away from Carlos. it all started on exriders/atvriders.com, trx250r section. I thought there was another site before we went to .net, but I may be misremembering

Interesting, and comments noted. I don't do drama on forums, and typically don't engage. Just way too old for that garbage. Either way, I appreciate the heads up.

I too am to old to engage. The certain guy you mention (I won’t repeat the the name) is a snake oil salesman. Shady from the beginning. There’s a reason why his “sponsored” riders left his “team”. More reasons why everyone in the R game (builders, producers of parts and common riders ) won’t deal with him. Hell, he “bought” a cheerleader following by giving away parts (know as nut swingers). His motor builder left (RIP Rob).
Everything said person sells is available elsewhere. Just ask. Parts are available everywhere. Once again just ask.
Yes I’m a moderator here and my opinion may be bias to some…feel free to search on the shady practices from the said company. I’m always available to talk in private if you like to get you up to speed on the “car sales man”. No offense to car salesman.
With that said….sorry for the long response. To answer your question start with the plate lined up. I think that’s where mine is at. I’ll pull the cover off and verify and report back.

This is my opinion of that company....

LMAO. I can't quite put my finger on it, but I feel there is some kind of point attempted to be made here. I'm sure I can do some digging and find some of the posts across the net.
All that being said, where is the best place to source things like billet parts? I don't like to wait a month or 3 due to production issues or backordered items. ESR, LED etc always seem to have waits and production dates. I have yet to see any changes on ESR's site with in stock, or even a hard production date on anything.

Check out “The Mad Scientist” section of our forum. Anything specific you are looking for?

just about everything billet you can think of!
now, in my opinion the CR igntion swap is a thing of the past. DRW is about ready to relase the zeel ignitions again. better power, lower cost, and you can run lights

croat1, the next thing i'll be looking for is a house, after my wife evicts me for my recent spending habits.
atvmxr, thanks for that site.

I also have a bdt plate and there’s 2 sets of holes and you’ll use the 01 obviously. I was told to turn the stator as far counter clockwise as possible to start. I ran it a little and the timing mark on the plug wasn’t quite right so I removed the little plate so I could retard it a tad more. That put the heat mark right on the bend of the plug strap.

If this method works for you and it makes the most power without causing detonation I would continue using it as a tuning tool.
I have been modifying and tuning two stroke engines for a little over 50 years and have not found this method to be an indicator that an optimum timing setting has been reached and is a safe timing setting. I try to use a method when tuning an engine that will indicate whether there was a power increase or decrease when changing the timing or jetting watching the top of the piston, combustion chamber, and spark for signs of the onset of very mild detonation. The methods I use to determine a change in power are: the dyno, the drag striip where E. T. and MPH is recorded and roll on acceleration testing using two vehicles of similar performance, on a surface of maximum traction and compare how the acceleration changes as tuning changes are made.
I want to play the devils advocate for a minute..
My testing has shown the heat mark that you mentioned on the ground strap will move to different parts of the ground strap with different styles of spark plugs of the same heat range with the same timing setting and making exactly the same power. The total length of the ground strap, the cross sectional area of the ground strap, the amount of mass in the threaded shell where the ground strap attaches, the alloy that the ground strap is made of and the combustion temperature are the main parameters that affect the temperature of the ground strap. The heat mark on the ground strap will also move with a change in coolant temperature and alloy the cylinder head is made of.

I’m just learning from what I read on forums and apply it if it sounds legit. Probably not the best way but I don’t know anyone with much knowledge of 2 strokes. I could see the coloring on the strap move as a changed the timing and it didn’t have any detonation that I could hear (not that I would probably notice it) and it didn’t run worse. I’m not looking for max performance and don’t race competitively so I guess what I’ve done so far has kept it from melting a piston after 1.5yrs riding every weekend on pump gas has worked. I didn’t know all this different things could change the mark on the strap so it’s really not a good way to adjust timing if you want it to be right. Thanks for taking the time to write that and I think there’s a lot of guys that tune like I have.

I have a brand new oem 2000 cr250 stator and flywheel for sale

I have also read about the heat strap mark, but, Jerry does make a lot of sense. Not all plugs are the same, and indeed, the mark should change (in my thoughts anyway) with a different temp plug carrying the heat away more efficiently. But Im far from any type of 2 stroke tuner. I know enough to keep myself away from the shop in general, but that ain't sayin' much...
