[how old is it]

It should be stamped on the fork tube. I was wondering the year of my 175dt and that's where I found it. Hope this is helpful to ya.

[tire question]

1.75? dont you mean 2.75?

go for it, it will fit with no clearance problems, dont see how there will be any graeat disadvantage with such a small change.

yeah sorry for the type-o but thanks for the reply

[tire question]

I was wondering, I have a 1980 175 dt as you know by now. I have a 1.75 x 21 inch tire on the front of my bike. Can I put a 3.00 x 21 on it? I have a chance to get a brand new one for $20. my 1.75 is partially dry rotted.

[HELP I have a 1980 175 DT]

Well I messed with the throttle screw. It helped some. Not a whole lot. I can safely ride now. Although it still stalls at idle. Not sure what it could be. Any insight further would be great.

Thanks for the welcome. Well even though both my Isuzu's are carb'd I have never worked on one. I'll check the throttle screw today though, and crank her up and see if she runs. I noticed the screw is out pretty far.

[HELP I have a 1980 175 DT]

Hello guys. I didn't see an introduction spot in the forum, but I need help asap. I'm in PA and I fear one of my last riding days will be tomorrow. Let me start with an intro. I'm a 26 yr old male. I am an Isuzu nut. I frequent in a few isuzu forums. I own a 1989 I-Mark and a 93 Isuzu pup and have owned MANY Isuzu vehicles. I own my 1980 175 DT along with a 1982 Honda 3 wheeler 125 bored 50 over. I'm still getting the 3 wheeler put back together. I love off roading and ATV riding. I got my 175 DT recently for $300 and it's in pretty good shape. It's missing somer lights and stuff and I'm putting some on it so I can street ride it also. Now with that aside here is my problem. My bike starts on the first kick every time. When I let off the throttle though she dies. I took it on a fit throwing hell ride today and it was scary as hell. If I let off the throttle completely she dies. So I rode with the throttle half tilt. What could it be? Like I said it starts on the first kick every time. I'm not too mechanically inclined so any help with pictures would be appreciated. I heard it could be the carb screw, and it could be running to lean. I don't know though. Any help would be greatly appreciated.
