Any link buy srv250 tci please i like the sound on motorcycle

[@iRidetas]

Nope, need to do your own research mate! If i can find one so can you!

[@fullcirclerepair2655]

Hey just wanted to say I do a lot of this type of stuff and we race Flat Track Motorcycles also sounds to me like you just need to rejet the carbs probably main jet and chatting

[@outie555]

That's a pretty interesting concept, especially as it gives you extra top speed. Potentially then with some tinkering you could get the lower rpms making more power but does sound like a fiddly job.

[@iRidetas]

Thanks, with the pool of knowledge from the guys that watch the videos i dont reckon it will be long before the bugs are worked out!

[@OldManTony]

Good experiment! I just love the sound of that bike, it always sounds like it’s a bigger bike than a 250!

[@iRidetas]

Thanks sounds cool doesnt it! 😀

[@KARMAkazeMoto]

Agreed, sounds great. Must be one of the best sounding 250s out there.

[@iRidetas]

Thanks mate! It is a fun little bike, my wife, who ive build it for, loves it!

[@spencerearl1996]

You might consider adding another shim or two under the needle, and go up one more size on the main. I'm running a 122.5 main and 20 pilot, with 3 washers under needle... I have an 08 xv250 and I live in Memphis,TN USA and my elevation is 380 ft and temp is in the upper 90s here (32+ c). I have a modified stock air box and filter, 2 into 2 shorty exhaust from amazon, carb slide mod, 16/38 gearing, and it pulls very hard to 65 mph (105kmh) and top out around 90 mph (145 kmh) in just under 0.5 km or a little over a 1/4 mile. Bike lacks some on top end and I am going to try this ignition on my bike and I think the bike will like 17/38 or even 17/36 more. I am hoping to get it to 100+ mph (160 kmh) with the ignition mod and some aero mods like a lower cowl scoop and a small windscreen.

[@dragata1]

Just a little tip man try 17/38 it blew my mind i ride in some steep hills here in GA So far engine wise i've done a large pancake air filter mod uses a high flow filter running open 2 stage exhaust 1 1/16" primary pipe into 2 1/2" duals out the rear to the rear tire Carb wise ported from 26mm to 28mm Jets are 120-20-2xshims Cams where done local got specs from a fellow xv250 rider they are .208/.208 had to do a little bit of grind work for clearances but increased the power a good bit just make sure you get the cam timing right also the bike cruises at 87mph no issues but i'd rather not ride a a light weight bike past that lol little to fast for me on a little "250"

[@fullcirclerepair2655]

Probably Main Jet and pilot jet possibly needle adjustment in the bike will run fantastic

[@iRidetas]

Rejet pilot and main, needle lift, clipping spring, drilling carb slide, intake and exhaust were already done by that stage! Played with gap etc. Just found it was a better more alround bike with the stock tci. 👍

[@MeBirdAdventures]

Informative video nice one thanks maybe a change in spark plugs just a suggestion either way it's coming along a treat 👍🇦🇺

[@iRidetas]

New plugs about a month ago! But thanks mate! 😀

[@czechmate9591]

Interesting man, great video very descriptive looking forward to seeing if you can get it running awesome with the TCI.

[@iRidetas]

I reckon with some help i should be able to get it singing!!

[@terrenceyap5937]

I had just replaced my stock carburetor with yamaha sr500 carburetor, instantly power increase by 20~30%. But intake manifold customize needed

[@iRidetas]

Nice. I always wondered about a pumper carby on one, too!

[@terrenceyap5937]

Might trying tci too

[@PavelGolts]

Difference between SRV and XV engines not only in TCI, cam shafts are more sporty on SRV, so if you wanna pump your XV engine with SRV TCI you would need SRV cam shafts.

[@iRidetas]

Yeah, and dual carbs etc. I realise this but the tci was a way to get ignition advance easily, but I sold the bike before I got it dialed in and could buy cams for it.

[@BOBBER400]

BLOODY EMPTY TANK GETTING IN THE WAY OF THE SKULLS VIDEO TIME.

[@iRidetas]

Haha the skull was pretty happy till it ran out 😀 cheers mate!

[@IanLomas]

great video

[@iRidetas]

Thanks

[@sheridancowling6257]

The problem with running the SRV250 TCI in the XV250 is the SRV uses 2 BDS26 carbs instead of one and they got different cam profiles. To take full advantage of the SRV TCI you need the cams to suit and an additional carburetor or a larger single. I've tried looking for some SRV cams but none appear to be available which sucks as I've just swapped out my 67k km motor for a 9k km one and I want to rebuild the original motor to SRV specs.

[@iRidetas]

srv tdi just has an advance of +5 on the timing to my knowledge. The real issue comes with the heads are different between xv250 and srv250 for those twin carbs. Not z simple swap unfortunately

[@nicholasschifano8615]

@@iRidetas would the srv cams fit in the virago without issues?

[@iRidetas]

To my knowledge yes but its been a few years since I research it, and couldn't find any at the time to buy!

[@AussieAnnihilation]

did you fix the low end problem? Im doing many of the same mods as you on my virago, i didnt even know this was an option until i saw this video!

[@iRidetas]

It's a lot of fiddling around for the gain! And they are hard to get!

[@supunperera2653]

Brother from where did you buy yamaha srv250 cdi unit? Um from Sri Lanka and um looking srv250 cdi unit.I couldn’t find Srv250 cdi unit from our country.so can you help me?

[@iRidetas]

Japan, Yahoo auctiions

[@maurorodrigues5061]

great video do you know of any adaptation you would have to make in the ingnition box of a virago 250

[@carlosrolo9987]

The virago original is a TCI too, right?

[@iRidetas]

Yes, correct

[@carlosrolo9987]

@@iRidetas thx m8

[@peterhannan3816]

Would changing the sprockets help bring it back to the lower end?

[@iRidetas]

video is about tci, please look up videos i made changing the sprockets to 17/40 in the playlist

[@Gruuvin1]

If you use a change of sprockets to get power on the low end, then you have to take it away from the top end.

[@KaungKaung-tr9rj]

l need the gv-250 cdi bro

[@Jordan.M23]

What is the tci for?

[@iRidetas]

Ignition! Spark and boom of the air fuel mixture!

[@Viper6-MotoVlogger]

It don’t think is seems worth it. Might need some tweaking.

[@iRidetas]

Yeah but the tinkering is the fun bit!!

[@Hum3lejak]

Next time try out the part you replace before you put bike back together so if the job you did did t work you don’t go through all the work of taking apart the bike again

[@iRidetas]

Sorry!!?? mate, how am i going to test the rideability of a cdi without reasembling the bike to ride?!?!
