Hey all, forgot to introduce myself on here after I joined up yesterday to ask some questions regarding my new Yamaha purchase. I live in in the Canadian Rockies in Alberta, Canada but grew up in Ontario about an hours drive from the big city of Toronto. I am not new to Yamaha, back in ON I had a 2000 Red and White Yamaha R6 and a 2001 Yamaha SXR600 snowmobile. I just purchased a 1980 DT175 because I have just had an itch to get back on two wheels but don't have the funds for anything new as I just started a family and purchased a project house. Oh ya, I also picked up an '81 PW50 and an '84 PW80 last summer that I am looking forward to restoring with my son who is currently just 8 1/2 months. Look forward to sharing info on those projects when I get a little more into them. Cheers, Jeff

Sorry, my bike DOES have the stock 49 tooth on the rear. I was thinking of putting a 53 or 54 tooth (whichever I can find) on the rear or a 15 tooth on the front because as it is now, 6 gear is useless on the road. I actually started losing speed when I shifted up to 6 because there was no power there to keep it climbing so I ended up dropping it back down to 5th just to hold it at 50mph. I understand the concept of sacrificing acceleration for top speed when raising the gearing, but this thing just seems like it was poorly geared from the factory, for this type of riding.

We had a DT200 up until 1996 here in Canada. I know a guy who has one back in Ontario where I grew up, not very common though, hope find one one day!

OK will have a look at how many teeth the front sprocket has and order a smaller one, that could help too. I have lots of great trails 5 mins from my door, just don't want to be a nuisance on the highway getting to the trails!

Air filter is good, pulled pipe off and removed baffle, that looks good as well. Was just about to remove carb and check reeds and I noticed that the rear sprocket is a 49 tooth. I believe the stock is a 45 i read somewhere? This could certainly be my issue. I think the not revving to to the redline is pretty normal on these bikes.

Hey everyone, Just bought a new to me 1980 Yamaha DT175. The bike is in mint condition and only has 600 original miles on it. The tac and speedo are in miles not sure if this is originally an American bike or if they all came that way, I live in Canada. Anyway, it runs really well and I have already taken it deep into the mountains, put about 50 miles on it and have no worries about the reliability of this thing. I am having an issue with the top speed. Guys on the internet are saying it should run at 120kph and mine tops out at around 50mph, roughly 80kph? It pulls pretty hard and idles well, but always struggles to get past 7000RPM. It will rev up 10,000rpm in neutral no problem however. I weigh about 200lbs and am a little big for the bike but I doubt that is the issue. Any suggestions? I have tried much yet. Will have a look at the air filter on it first I think. Thanks in advance.
