Dirt track weapon....well sort of..

[gerpster]

Ok spent most of today getting the TS sorted..see the latest pic attached. This was a farm bike with only 7000kms on it but it was filthy and covered in crap and partly disassembled. The PO had "carby problems" and sure enough despite my best efforts the carby still aint right....bummer!!!   
Decided to stick with the current trials tyres as they hold air ok and aren't too bad after all when cleaned up a bit...hopefully they will do for a few practice sessions.
But I now may need a TS185 carby....hmmmm..can anyone help??? Will pay...will post in the wanted section too....

Cheers....

I had a lot of dramas with my TS185ER carbie, I soaked it in fresh thinners and fitted one of these...

Hey noice pipe....shame I can't afford it but wouldn't it be wasted on a TS185? Or are they not as bad as I think??   

[cyclegod]

Three restrictions on TS185ER's

1, CDI is rev limited to about 7500 under load (replace with RM125 79/80)
2, The exhaust and muffler (mostly exhaust)
3, Porting, especially the intake side which is further restricted by the tiny strangled airbox
    (open up the port to the reed cage and fit aftermarket PE250 reeds with no stoppers)

[Doc]

Good onya Greg, not a bad looking TS ya have there, your invitation to join Suzuki Central and The Mighty TS Men will be forwarded shortly

That eBay pipe wouldn't fit the ER model as claimed anyway..for a start they are centre port exhaust and the pipe is for the early sideport single downtube frame. Apparently the stock pipe isn't 'too bad' CG but obviously could be improved. The gun mod I've been told by a very reliable source is remove 1 third of the flywheel weight, shorten the magnet screws, bolt her back together and it'll go like a cut snake without affecting reliability.

Hey Chris have a closer look at that pipe  its clearly for the center port engine, the mounts are a dead give away too

I'll be starting a 185 project soon. Anyone got the gearbox ratio's?.
I might start a blow by blow build up thread, Doc the pipes are shite, the flywheel is massive but that's not a bad thing,power reed can be fixed, airbox belongs in the skip.The real restriction is the exhaust port which I have some big plans for

Heres what I gave Pokey for the early 185, but the ER still uses the same output shaft and the input shaft is only shorter on the clutch hub end so all gears will fit.

Hey pokey, heres a breakdown of my TS/TM185 project gearbox
(YES!! you inspired it  )

RM125S straight-cut primary and basket 18t-61t (19t-61t stock185)
stock 185 input and output shafts

with 1st drive (14t stock shaft)
      2nd drive (17t from tm/rm125 (16t stock185))
      3rd drive  (20t stock 185)
      4th drive  (22t from tm/rm125 (23t stock185))
      5th drive  (25t stock 185)

      1st driven (30t from tm/rm125(33t stock 185))
      2nd driven (27t from tm/rm125(29t stock 185))
      3rd driven (25t stock 185)
      4th driven (23t stock 185)
      5th driven (21t from tm/rm125(20t stock 185))

This is what is going into my bottom end as the RM basket gets 2 extra plates and still fits inside the clutch cover, which is a 1976
type that looks the same as the TM ones. The engine is going into a TM 125 chassis that I picked up at the swapmeet this year
I have good o.e.m forks, tank, seat, wheels and a RM125S ignition to go in it, I'll make my own pipe and only mildly port the cylinder. I will also shave a few mm of the bottom of the piston skirt to increase the intake port timing (you have to take 5mm of the bottom of ts125 pistons to use them in TM125's) so I will start small and work my way up from there. I'll post some pics when I have more than a pile of bits to take pictures of.

I intend my TS/TM to look as close to stock as possible in the hope no one will notice

Ok so if I ditch the airbox what's the best alternative....pod filter...unifilter....?   

Just trying to keep it simple at the moment...   

Cheers..

sounds good. looks like i will have to put mine back together. so the RM 125 ignition is definitly the go then? any one got one of those for sale? what about a PE 175 CDI. i think im on the hunt for a 1980 RM 125 CDI now but i dont know what buyin used ones is like, prefer a nos

cyclegod, does that give the bike longer legs in top gear? i was wanting to put a higher fith gear ratio im my 185 for longer legs but i couldnt find anthing. can you tell me what yr TM those ratios are from and part number of the cogs?

[LWC82PE]

whats the go with that pipe will it fit centre port or not? i reckon i want it!

i got another air box cover and drilled about half a dozen 1inch holes it it and put some white brothers air box vents in. i also removed the intake snorkel and run a unifiter on stock cage

[cyclegod]

If you look at the photos of the pipe you can see that the mounts are in the correct position for the center port TS/DS/TF185 77-on

As for the gears, well they are from TM125 all years and 1975 RM 125 (http://www.alpha-sports.com/suzuki_parts.htm) and give a close ratio box so longer legs is just a matter of setting the final ratio right 12/39(3.25) is standard,
factory options at max would be 14/37 (2.64)

[LWC82PE]

so you have geared it down. ive mucked around with final ratios but i want to change just the 5th combo. to make it higher i need a larger drive gear and smaller driven gear. thats right isnt it? that pipe is tempting but im not sure if my side number plate will fit over it as the ER pipe is kind of flat. now when i look at it the header part of that pipe is totally different to mine. i cant see how it would fit. the front loop doesnt bend in the right direction as the standard pipe, unless its made to be different like that. my stock pipe comes out the barrel and then turns out to the right and then hooks around and up under the tank. that one looks like it has no turn out to the right and it looks like it goes straight up

Only the stock pipe can be used if you want to fit a standard ER185 side cover or alternately mount an oval plate below muffler/pipe position (ala early huskies) J&R pipes tend to NOT follow the stock shape at the header but it looks to me like it would fit fine (I saw this pipe for sale before the current seller bought it and it had better photos including one of it on a bike)
